+# Code of Conduct
+
+`nvm`, as a member project of the OpenJS Foundation, uses [Contributor Covenant v1.4](https://www.contributor-covenant.org/version/1/4/code-of-conduct) as their code of conduct. The full text is included [below](#contributor-covenant-code-of-conduct) in English, and translations are available from the Contributor Covenant organisation:
+
+- [contributor-covenant.org/translations](https://www.contributor-covenant.org/translations)
+- [github.com/ContributorCovenant](https://github.com/ContributorCovenant/contributor_covenant/tree/release/content/version/1/4)
+
+Refer to the sections on reporting and escalation in this document for the specific emails that can be used to report and escalate issues.
+
+## Reporting
+
+### Project Spaces
+
+For reporting issues in spaces related to `nvm` please use the email `ljharb@gmail.com`. `nvm` handles CoC issues related to the spaces that it maintains. Projects maintainers commit to:
+
+- maintain the confidentiality with regard to the reporter of an incident
+- to participate in the path for escalation as outlined in
+  the section on Escalation when required.
+
+### Foundation Spaces
+
+For reporting issues in spaces managed by the OpenJS Foundation, for example, repositories within the OpenJS organization, use the email `report@lists.openjsf.org`. The Cross Project Council (CPC) is responsible for managing these reports and commits to:
+
+- maintain the confidentiality with regard to the reporter of an incident
+- to participate in the path for escalation as outlined in
+  the section on Escalation when required.
+
+## Escalation
+
+The OpenJS Foundation maintains a Code of Conduct Panel (CoCP). This is a foundation-wide team established to manage escalation when a reporter believes that a report to a member project or the CPC has not been properly handled. In order to escalate to the CoCP send an email to `coc-escalation@lists.openjsf.org`.
+
+For more information, refer to the full [Code of Conduct governance document](https://github.com/openjs-foundation/cross-project-council/blob/master/CODE_OF_CONDUCT.md).

+
+## Contributor Covenant Code of Conduct
+
+### Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+### Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+### Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+### Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+### Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at the email addresses listed above in
+the [Reporting](#reporting) and [Escalation](#escalation) sections. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an
+incident. Further details of specific enforcement policies may be posted
+separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [https://www.contributor-covenant.org/version/1/4/code-of-conduct/](https://www.contributor-covenant.org/version/1/4/code-of-conduct/)

+# `nvm` Charter
+
+nvm is a version manager for Node.js, designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and Windows WSL.
+
+## Section 0: Guiding Principles
+
+The `nvm` project is part of the [OpenJS Foundation][openjs foundation], which operates transparently, openly, collaboratively, and ethically. Project proposals, timelines, and status must not merely be open, but also easily visible to outsiders.
+
+## Section 1: Scope
+
+`nvm` is a node version manager, focused on making it easy to install and manage multiple Node.js versions. Any features related to managing the installation and removal of Node.js on any node-supported platform are potentially in scope.
+
+## Section 2: Relationship with OpenJS Foundation CPC.
+
+Technical leadership for the projects within the [OpenJS Foundation][openjs foundation] is delegated to the projects through their project charters by the [OpenJS Foundation Cross-Project Council](https://openjsf.org/about/governance/) (CPC). In the case of the `nvm` project, it is delegated to the [`nvm` Maintainers](README.md#maintainers) (the “Maintainers”). The OpenJS Foundation's business leadership is the Board of Directors (the “Board”).
+
+This `nvm` Charter reflects a carefully constructed balanced role for the Maintainers and the CPC in the governance of the OpenJS Foundation. The charter amendment process is for the Maintainers to propose changes using simple majority of the full Maintainers, the proposed changes being subject to review and approval by the CPC. The CPC may additionally make amendments to the project charter at any time, though the CPC will not interfere with day-to-day discussions, votes or meetings of the Maintainers.
+
+### 2.1 Other Formal Project Relationships
+
+Section Intentionally Left Blank
+
+## Section 3: `nvm`'s Maintainers Governing Body
+
+`nvm` is governed by its [maintainers](README.md#maintainers).
+
+## Section 4: Roles & Responsibilities
+
+The roles and responsibilities of `nvm`'s Maintainers are described in [GOVERNANCE.md](./GOVERNANCE.md).
+
+### Section 4.1 Project Operations & Management

+Section Intentionally Left Blank
+
+## Section 5: Definitions
+
+  - *Contributors*: contribute code or other artifacts, but do not have the right to commit to the codebase. Contributors work with the project’s maintainers to have code committed to the code base. A Contributor may be promoted to a Maintainer by the Maintainers. Contributors should rarely be encumbered by the Maintainers and never by the CPC or OpenJS Foundation Board.
+
+  - *Maintainers*: Contributors with any kind of decision-making authority in the project.

-# Node Version Manager [![Build Status](https://travis-ci.org/creationix/nvm.svg?branch=master)][3]
-
-## Installation
-
-First you'll need to make sure your system has a c++ compiler. For OSX, XCode will work, for Ubuntu, the build-essential and libssl-dev packages work.
-
-Note: `nvm` does not support Windows (see [#284](https://github.com/creationix/nvm/issues/284)). Two alternatives exist, which are neither supported nor developed by us:
- - [nvmw](https://github.com/hakobera/nvmw)
- - [nvm-windows](https://github.com/coreybutler/nvm-windows)
-
-Note: `nvm` does not support [Fish] either (see [#303](https://github.com/creationix/nvm/issues/303)). An alternative exists, which is neither supported nor developed by us:
- - [bass](https://github.com/edc/bass) allows to use utilities written for Bash in fish shell
-
-### Install script
-
-To install you could use the [install script][2] using cURL:
-
-    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.28.0/install.sh | bash
-
-or Wget:
-
-    wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.28.0/install.sh | bash
-
-<sub>The script clones the nvm repository to `~/.nvm` and adds the source line to your profile (`~/.bash_profile`, `~/.zshrc` or `~/.profile`).</sub>
-
-You can customize the install source, directory and profile using the `NVM_SOURCE`, `NVM_DIR`, and `PROFILE` variables.
-Eg: `curl ... | NVM_DIR=/usr/local/nvm bash` for a global install.
-
-<sub>*NB. The installer can use `git`, `curl`, or `wget` to download `nvm`, whatever is available.*</sub>
-
-### Manual install
-
-For manual install create a folder somewhere in your filesystem with the `nvm.sh` file inside it. I put mine in a folder called `nvm`.
-
-Or if you have `git` installed, then just clone it, and check out the latest version:
-
-    git clone https://github.com/creationix/nvm.git ~/.nvm && cd ~/.nvm && git checkout `git describe --abbrev=0 --tags`
-
-To activate nvm, you need to source it from your shell:
-
-    . ~/.nvm/nvm.sh
-
-I always add this line to my `~/.bashrc`, `~/.profile`, or `~/.zshrc` file to have it automatically sourced upon login.
-Often I also put in a line to use a specific version of node.
-
-## Usage
-
-You can create an `.nvmrc` file containing version number in the project root directory (or any parent directory).
-`nvm use`, `nvm install`, `nvm exec`, `nvm run`, and `nvm which` will all respect an `.nvmrc` file when a version is not supplied.
-
-To download, compile, and install the latest v0.10.x release of node, do this:
-
-    nvm install 0.10
-
-And then in any new shell just use the installed version:
-
-    nvm use 0.10
-
-Or you can just run it:
-
-    nvm run 0.10 --version
-
-Or, you can run any arbitrary command in a subshell with the desired version of node:
-
-    nvm exec 0.10 node --version
-
-You can also get the path to the executable to where it was installed:
-
-    nvm which 0.10
-
-In place of a version pointer like "0.10", you can use the special default aliases "stable" and "unstable":
-
-    nvm install stable
-    nvm install unstable
-    nvm use stable
-    nvm run unstable --version
-
-If you want to install a new version of Node.js and migrate npm packages from a previous version:
-
-    nvm install node --reinstall-packages-from=node
-
-This will first use "nvm version node" to identify the current version you're migrating packages from. Then it resolves the new version to install from the remote server and installs it. Lastly, it runs "nvm reinstall-packages" to reinstall the npm packages from your prior version of Node to the new one.
-
-You can also install and migrate npm packages from specific versions of Node like this:
-
-    nvm install v0.10.40 --reinstall-packages-from=0.10.39
-    nvm install v0.12.7 --reinstall-packages-from=0.12.6
-
-If you want to install [io.js](https://github.com/iojs/io.js/):
-
-    nvm install iojs
-
-If you want to install a new version of io.js and migrate npm packages from a previous version:
-
-    nvm install iojs --reinstall-packages-from=iojs
-
-The same guidelines mentioned for migrating npm packages in Node.js are applicable to io.js.
-
-If you want to use the system-installed version of node, you can use the special default alias "system":
-
-    nvm use system
-    nvm run system --version
-
-If you want to see what versions are installed:
-
-    nvm ls
-
-If you want to see what versions are available to install:
-
-    nvm ls-remote
-
-To restore your PATH, you can deactivate it.
-
-    nvm deactivate
-
-To set a default Node version to be used in any new shell, use the alias 'default':
-
-    nvm alias default stable
-
-To use a mirror of the node binaries, set `$NVM_NODEJS_ORG_MIRROR`:
-
-    export NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist
-    nvm install 0.10
-
-    NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 0.10
-
-To use a mirror of the iojs binaries, set `$NVM_IOJS_ORG_MIRROR`:
-
-    export NVM_IOJS_ORG_MIRROR=https://iojs.org/dist
-    nvm install iojs-v1.0.3
-
-    NVM_IOJS_ORG_MIRROR=https://iojs.org/dist nvm install iojs-v1.0.3
-
-`nvm use` will not, by default, create a "current" symlink. Set `$NVM_SYMLINK_CURRENT` to "true" to enable this behavior, which is sometimes useful for IDEs.

-
-## Running tests
-Tests are written in [Urchin]. Install Urchin (and other dependencies) like so:
-
-    npm install
-
-There are slow tests and fast tests. The slow tests do things like install node
-and check that the right versions are used. The fast tests fake this to test
-things like aliases and uninstalling. From the root of the nvm git repository,
-run the fast tests like this.
-
-    npm run test/fast
-
-Run the slow tests like this.
-
-    npm run test/slow
-
-Run all of the tests like this
-
-    npm test
-
-Nota bene: Avoid running nvm while the tests are running.
-
-## Bash completion
-
-To activate, you need to source `bash_completion`:
-
-  	[[ -r $NVM_DIR/bash_completion ]] && . $NVM_DIR/bash_completion
-
-Put the above sourcing line just below the sourcing line for NVM in your profile (`.bashrc`, `.bash_profile`).
-
-### Usage
-
-nvm
-
-	$ nvm [tab][tab]
-    alias               deactivate          install             ls                  run                 unload
-    clear-cache         exec                list                ls-remote           unalias             use
-    current             help                list-remote         reinstall-packages  uninstall           version
-
-nvm alias
-
-	$ nvm alias [tab][tab]
-	default
-
-	$ nvm alias my_alias [tab][tab]
-	v0.6.21        v0.8.26       v0.10.28
-
-nvm use
-
-	$ nvm use [tab][tab]
-	my_alias        default        v0.6.21        v0.8.26       v0.10.28
-
-nvm uninstall
-
-	$ nvm uninstall [tab][tab]
-	my_alias        default        v0.6.21        v0.8.26       v0.10.28
-
-## Compatibility Issues
-`nvm` will encounter some issues if you have some non-default settings set. (see [#606](/../../issues/606))
-The following are known to cause issues:
-
-Inside `~/.npmrc`
-```
-prefix='some/path'
-```
-Environment Variables:
-```
-$NPM_CONFIG_PREFIX
-$PREFIX
-```
-
-## Problems
-
-If you try to install a node version and the installation fails, be sure to delete the node downloads from src (~/.nvm/src/) or you might get an error when trying to reinstall them again or you might get an error like the following:
-
-    curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.
-
-Where's my 'sudo node'? Check out this link:
-
-https://github.com/creationix/nvm/issues/43
-
-On Arch Linux and other systems using python3 by default, before running *install* you need to
-
-      export PYTHON=python2
-
-After the v0.8.6 release of node, nvm tries to install from binary packages. But in some systems, the official binary packages don't work due to incompatibility of shared libs. In such cases, use `-s` option to force install from source:
-
-    nvm install -s 0.8.6

+## Intro
+
+`nvm` allows you to quickly install and use different versions of node via the command line.
+
+**Example:**
+```sh
+$ nvm use 16
+Now using node v16.9.1 (npm v7.21.1)
+$ node -v
+v16.9.1
+$ nvm use 14
+Now using node v14.18.0 (npm v6.14.15)
+$ node -v
+v14.18.0
+$ nvm install 12
+Now using node v12.22.6 (npm v6.14.5)
+$ node -v
+v12.22.6
+```
+
+Simple as that!
+
+
+## About
+nvm is a version manager for [node.js](https://nodejs.org/en/), designed to be installed per-user, and invoked per-shell. `nvm` works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and [windows WSL](https://github.com/nvm-sh/nvm#important-notes).
+
+<a id="installation-and-update"></a>
+<a id="install-script"></a>
+## Installing and Updating
+
+### Install & Update Script
+
+To **install** or **update** nvm, you should run the [install script][2]. To do that, you may either download and run the script manually, or use the following cURL or Wget command:
+```sh
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+```
+```sh
+wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+```
+
+Running either of the above commands downloads a script and runs it. The script clones the nvm repository to `~/.nvm`, and attempts to add the source lines from the snippet below to the correct profile file (`~/.bash_profile`, `~/.zshrc`, `~/.profile`, or `~/.bashrc`).
+
+<a id="profile_snippet"></a>
+```sh
+export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
+```
+
+#### Additional Notes
+
+- If the environment variable `$XDG_CONFIG_HOME` is present, it will place the `nvm` files there.</sub>
+
+- You can add `--no-use` to the end of the above script (...`nvm.sh --no-use`) to postpone using `nvm` until you manually [`use`](#usage) it.
+
+- You can customize the install source, directory, profile, and version using the `NVM_SOURCE`, `NVM_DIR`, `PROFILE`, and `NODE_VERSION` variables.
+Eg: `curl ... | NVM_DIR="path/to/nvm"`. Ensure that the `NVM_DIR` does not contain a trailing slash.
+
+- The installer can use `git`, `curl`, or `wget` to download `nvm`, whichever is available.
+
+#### Troubleshooting on Linux
+
+On Linux, after running the install script, if you get `nvm: command not found` or see no feedback from your terminal after you type `command -v nvm`, simply close your current terminal, open a new terminal, and try verifying again.
+Alternatively, you can run the following commands for the different shells on the command line:
+
+*bash*: `source ~/.bashrc`
+
+*zsh*: `source ~/.zshrc`
+
+*ksh*: `. ~/.profile`
+
+These should pick up the `nvm` command.
+
+#### Troubleshooting on macOS
+
+Since OS X 10.9, `/usr/bin/git` has been preset by Xcode command line tools, which means we can't properly detect if Git is installed or not. You need to manually install the Xcode command line tools before running the install script, otherwise, it'll fail. (see [#1782](https://github.com/nvm-sh/nvm/issues/1782))
+
+If you get `nvm: command not found` after running the install script, one of the following might be the reason:
+
+  - Since macOS 10.15, the default shell is `zsh` and nvm will look for `.zshrc` to update, none is installed by default. Create one with `touch ~/.zshrc` and run the install script again.
+
+  - If you use bash, the previous default shell, your system may not have a `.bash_profile` file where the command is set up. Create one with `touch ~/.bash_profile` and run the install script again. Then, run `source ~/.bash_profile` to pick up the `nvm` command.
+
+  - You have previously used `bash`, but you have `zsh` installed. You need to manually add [these lines](#manual-install) to `~/.zshrc` and run `. ~/.zshrc`.
+
+  - You might need to restart your terminal instance or run `. ~/.nvm/nvm.sh`. Restarting your terminal/opening a new tab/window, or running the source command will load the command and the new configuration.
+
+  - If the above didn't help, you might need to restart your terminal instance. Try opening a new tab/window in your terminal and retry.
+
+If the above doesn't fix the problem, you may try the following:
+
+  - If you use bash, it may be that your `.bash_profile` (or `~/.profile`) does not source your `~/.bashrc` properly. You could fix this by adding `source ~/<your_profile_file>` to it or follow the next step below.
+
+  - Try adding [the snippet from the install section](#profile_snippet), that finds the correct nvm directory and loads nvm, to your usual profile (`~/.bash_profile`, `~/.zshrc`, `~/.profile`, or `~/.bashrc`).
+
+  - For more information about this issue and possible workarounds, please [refer here](https://github.com/nvm-sh/nvm/issues/576)
+
+#### Ansible
+
+You can use a task:
+
+```yaml
+- name: nvm
+  shell: >
+    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+  args:
+    creates: "{{ ansible_env.HOME }}/.nvm/nvm.sh"
+```
+
+### Verify Installation
+
+To verify that nvm has been installed, do:
+
+```sh
+command -v nvm
+```
+
+which should output `nvm` if the installation was successful. Please note that `which nvm` will not work, since `nvm` is a sourced shell function, not an executable binary.
+
+**Note:** On Linux, after running the install script, if you get `nvm: command not found` or see no feedback from your terminal after you type `command -v nvm`, simply close your current terminal, open a new terminal, and try verifying again.
+
+### Important Notes
+
+If you're running a system without prepackaged binary available, which means you're going to install nodejs or io.js from its source code, you need to make sure your system has a C++ compiler. For OS X, Xcode will work, for Debian/Ubuntu based GNU/Linux, the `build-essential` and `libssl-dev` packages work.
+
+**Note:** `nvm` also support Windows in some cases. It should work through WSL (Windows Subsystem for Linux) depending on the version of WSL. It should also work with [GitBash](https://gitforwindows.org/) (MSYS) or [Cygwin](https://cygwin.com). Otherwise, for Windows, a few alternatives exist, which are neither supported nor developed by us:
+
+  - [nvm-windows](https://github.com/coreybutler/nvm-windows)
+  - [nodist](https://github.com/marcelklehr/nodist)
+  - [nvs](https://github.com/jasongin/nvs)
+
+**Note:** `nvm` does not support [Fish] either (see [#303](https://github.com/nvm-sh/nvm/issues/303)). Alternatives exist, which are neither supported nor developed by us:
+
+  - [bass](https://github.com/edc/bass) allows you to use utilities written for Bash in fish shell
+  - [fast-nvm-fish](https://github.com/brigand/fast-nvm-fish) only works with version numbers (not aliases) but doesn't significantly slow your shell startup
+  - [plugin-nvm](https://github.com/derekstavis/plugin-nvm) plugin for [Oh My Fish](https://github.com/oh-my-fish/oh-my-fish), which makes nvm and its completions available in fish shell
+  - [fnm](https://github.com/fisherman/fnm) - [fisherman](https://github.com/fisherman/fisherman)-based version manager for fish
+  - [fish-nvm](https://github.com/FabioAntunes/fish-nvm) - Wrapper around nvm for fish, delays sourcing nvm until it's actually used.
+
+**Note:** We still have some problems with FreeBSD, because there is no official pre-built binary for FreeBSD, and building from source may need [patches](https://www.freshports.org/www/node/files/patch-deps_v8_src_base_platform_platform-posix.cc); see the issue ticket:
+
+  - [[#900] [Bug] nodejs on FreeBSD may need to be patched](https://github.com/nvm-sh/nvm/issues/900)
+  - [nodejs/node#3716](https://github.com/nodejs/node/issues/3716)
+
+**Note:** On OS X, if you do not have Xcode installed and you do not wish to download the ~4.3GB file, you can install the `Command Line Tools`. You can check out this blog post on how to just that:
+
+  - [How to Install Command Line Tools in OS X Mavericks & Yosemite (Without Xcode)](http://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x/)
+
+**Note:** On OS X, if you have/had a "system" node installed and want to install modules globally, keep in mind that:
+
+  - When using `nvm` you do not need `sudo` to globally install a module with `npm -g`, so instead of doing `sudo npm install -g grunt`, do instead `npm install -g grunt`
+  - If you have an `~/.npmrc` file, make sure it does not contain any `prefix` settings (which is not compatible with `nvm`)
+  - You can (but should not?) keep your previous "system" node install, but `nvm` will only be available to your user account (the one used to install nvm). This might cause version mismatches, as other users will be using `/usr/local/lib/node_modules/*` VS your user account using `~/.nvm/versions/node/vX.X.X/lib/node_modules/*`
+
+Homebrew installation is not supported. If you have issues with homebrew-installed `nvm`, please `brew uninstall` it, and install it using the instructions below, before filing an issue.
+
+**Note:** If you're using `zsh` you can easily install `nvm` as a zsh plugin. Install [`zsh-nvm`](https://github.com/lukechilds/zsh-nvm) and run `nvm upgrade` to upgrade.
+
+**Note:** Git versions before v1.7 may face a problem of cloning `nvm` source from GitHub via https protocol, and there is also different behavior of git before v1.6, and git prior to [v1.17.10](https://github.com/git/git/commit/5a7d5b683f869d3e3884a89775241afa515da9e7) can not clone tags, so the minimum required git version is v1.7.10. If you are interested in the problem we mentioned here, please refer to GitHub's [HTTPS cloning errors](https://help.github.com/articles/https-cloning-errors/) article.
+
+### Git Install
+
+If you have `git` installed (requires git v1.7.10+):
+
+1. clone this repo in the root of your user profile
+  - `cd ~/` from anywhere then `git clone https://github.com/nvm-sh/nvm.git .nvm`
+1. `cd ~/.nvm` and check out the latest version with `git checkout v0.39.0`
+1. activate `nvm` by sourcing it from your shell: `. ./nvm.sh`
+
+Now add these lines to your `~/.bashrc`, `~/.profile`, or `~/.zshrc` file to have it automatically sourced upon login:
+(you may have to add to more than one of the above files)
+
+```sh
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
+[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
+```
+
+### Manual Install
+
+For a fully manual install, execute the following lines to first clone the `nvm` repository into `$HOME/.nvm`, and then load `nvm`:
+
+```sh
+export NVM_DIR="$HOME/.nvm" && (
+  git clone https://github.com/nvm-sh/nvm.git "$NVM_DIR"
+  cd "$NVM_DIR"
+  git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" $(git rev-list --tags --max-count=1)`
+) && \. "$NVM_DIR/nvm.sh"
+```
+
+Now add these lines to your `~/.bashrc`, `~/.profile`, or `~/.zshrc` file to have it automatically sourced upon login:
+(you may have to add to more than one of the above files)
+
+```sh
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
+[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
+```
+
+### Manual Upgrade
+
+For manual upgrade with `git` (requires git v1.7.10+):
+
+1. change to the `$NVM_DIR`
+1. pull down the latest changes
+1. check out the latest version
+1. activate the new version
+
+```sh
+(
+  cd "$NVM_DIR"
+  git fetch --tags origin
+  git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" $(git rev-list --tags --max-count=1)`
+) && \. "$NVM_DIR/nvm.sh"
+```
+
+## Usage
+
+To download, compile, and install the latest release of node, do this:
+
+```sh
+nvm install node # "node" is an alias for the latest version
+```
+
+To install a specific version of node:
+
+```sh
+nvm install 14.7.0 # or 16.3.0, 12.22.1, etc
+```
+
+The first version installed becomes the default. New shells will start with the default version of node (e.g., `nvm alias default`).
+
+You can list available versions using `ls-remote`:
+
+```sh
+nvm ls-remote
+```
+
+And then in any new shell just use the installed version:
+
+```sh
+nvm use node
+```
+
+Or you can just run it:
+
+```sh
+nvm run node --version
+```
+
+Or, you can run any arbitrary command in a subshell with the desired version of node:
+
+```sh
+nvm exec 4.2 node --version
+```
+
+You can also get the path to the executable to where it was installed:
+
+```sh
+nvm which 12.22
+```
+
+In place of a version pointer like "14.7" or "16.3" or "12.22.1", you can use the following special default aliases with `nvm install`, `nvm use`, `nvm run`, `nvm exec`, `nvm which`, etc:
+
+  - `node`: this installs the latest version of [`node`](https://nodejs.org/en/)
+  - `iojs`: this installs the latest version of [`io.js`](https://iojs.org/en/)
+  - `stable`: this alias is deprecated, and only truly applies to `node` `v0.12` and earlier. Currently, this is an alias for `node`.
+  - `unstable`: this alias points to `node` `v0.11` - the last "unstable" node release, since post-1.0, all node versions are stable. (in SemVer, versions communicate breakage, not stability).
+
+### Long-term Support
+
+Node has a [schedule](https://github.com/nodejs/Release#release-schedule) for long-term support (LTS) You can reference LTS versions in aliases and `.nvmrc` files with the notation `lts/*` for the latest LTS, and `lts/argon` for LTS releases from the "argon" line, for example. In addition, the following commands support LTS arguments:
+
+  - `nvm install --lts` / `nvm install --lts=argon` / `nvm install 'lts/*'` / `nvm install lts/argon`
+  - `nvm uninstall --lts` / `nvm uninstall --lts=argon` / `nvm uninstall 'lts/*'` / `nvm uninstall lts/argon`
+  - `nvm use --lts` / `nvm use --lts=argon` / `nvm use 'lts/*'` / `nvm use lts/argon`
+  - `nvm exec --lts` / `nvm exec --lts=argon` / `nvm exec 'lts/*'` / `nvm exec lts/argon`
+  - `nvm run --lts` / `nvm run --lts=argon` / `nvm run 'lts/*'` / `nvm run lts/argon`
+  - `nvm ls-remote --lts` / `nvm ls-remote --lts=argon` `nvm ls-remote 'lts/*'` / `nvm ls-remote lts/argon`
+  - `nvm version-remote --lts` / `nvm version-remote --lts=argon` / `nvm version-remote 'lts/*'` / `nvm version-remote lts/argon`
+
+Any time your local copy of `nvm` connects to https://nodejs.org, it will re-create the appropriate local aliases for all available LTS lines. These aliases (stored under `$NVM_DIR/alias/lts`), are managed by `nvm`, and you should not modify, remove, or create these files - expect your changes to be undone, and expect meddling with these files to cause bugs that will likely not be supported.
+
+To get the latest LTS version of node and migrate your existing installed packages, use
+
+```sh
+nvm install 'lts/*' --reinstall-packages-from=current
+```
+
+### Migrating Global Packages While Installing
+
+If you want to install a new version of Node.js and migrate npm packages from a previous version:
+
+```sh
+nvm install node --reinstall-packages-from=node
+```
+
+This will first use "nvm version node" to identify the current version you're migrating packages from. Then it resolves the new version to install from the remote server and installs it. Lastly, it runs "nvm reinstall-packages" to reinstall the npm packages from your prior version of Node to the new one.
+
+You can also install and migrate npm packages from specific versions of Node like this:
+
+```sh
+nvm install 6 --reinstall-packages-from=5
+nvm install v4.2 --reinstall-packages-from=iojs
+```
+
+Note that reinstalling packages _explicitly does not update the npm version_ — this is to ensure that npm isn't accidentally upgraded to a broken version for the new node version.
+
+To update npm at the same time add the `--latest-npm` flag, like this:
+
+```sh
+nvm install 'lts/*' --reinstall-packages-from=default --latest-npm
+```
+
+or, you can at any time run the following command to get the latest supported npm version on the current node version:
+```sh
+nvm install-latest-npm
+```
+
+If you've already gotten an error to the effect of "npm does not support Node.js", you'll need to (1) revert to a previous node version (`nvm ls` & `nvm use <your latest _working_ version from the ls>`, (2) delete the newly created node version (`nvm uninstall <your _broken_ version of node from the ls>`), then (3) rerun your `nvm install` with the `--latest-npm` flag.
+
+
+### Default Global Packages From File While Installing
+
+If you have a list of default packages you want installed every time you install a new version, we support that too -- just add the package names, one per line, to the file `$NVM_DIR/default-packages`. You can add anything npm would accept as a package argument on the command line.
+
+```sh
+# $NVM_DIR/default-packages
+
+rimraf
+object-inspect@1.0.2
+stevemao/left-pad
+```
+
+### io.js
+
+If you want to install [io.js](https://github.com/iojs/io.js/):
+
+```sh
+nvm install iojs
+```
+
+If you want to install a new version of io.js and migrate npm packages from a previous version:
+
+```sh
+nvm install iojs --reinstall-packages-from=iojs
+```
+
+The same guidelines mentioned for migrating npm packages in node are applicable to io.js.
+
+### System Version of Node
+
+If you want to use the system-installed version of node, you can use the special default alias "system":
+
+```sh
+nvm use system
+nvm run system --version
+```
+
+### Listing Versions
+
+If you want to see what versions are installed:
+
+```sh
+nvm ls
+```
+
+If you want to see what versions are available to install:
+
+```sh
+nvm ls-remote
+```
+
+### Setting Custom Colors
+
+You can set five colors that will be used to display version and alias information. These colors replace the default colors.
+  Initial colors are: g b y r e
+
+  Color codes:
+
+    r/R = red / bold red
+
+    g/G = green / bold green
+
+    b/B = blue / bold blue
+
+    c/C = cyan / bold cyan
+
+    m/M = magenta / bold magenta
+
+    y/Y = yellow / bold yellow
+
+    k/K = black / bold black
+
+    e/W = light grey / white
+
+```sh
+nvm set-colors rgBcm
+```
+
+#### Persisting custom colors
+
+If you want the custom colors to persist after terminating the shell, export the NVM_COLORS variable in your shell profile. For example, if you want to use cyan, magenta, green, bold red and bold yellow, add the following line:
+
+```sh
+export NVM_COLORS='cmgRY'
+```
+
+#### Suppressing colorized output
+
+`nvm help (or -h or --help)`, `nvm ls`, `nvm ls-remote` and `nvm alias` usually produce colorized output. You can disable colors with the `--no-colors` option (or by setting the environment variable `TERM=dumb`):
+
+```sh
+nvm ls --no-colors
+nvm help --no-colors
+TERM=dumb nvm ls
+```
+
+#### Restoring PATH
+To restore your PATH, you can deactivate it:
+
+```sh
+nvm deactivate
+```
+
+#### Set default node version
+To set a default Node version to be used in any new shell, use the alias 'default':
+
+```sh
+nvm alias default node
+```
+
+#### Use a mirror of node binaries
+To use a mirror of the node binaries, set `$NVM_NODEJS_ORG_MIRROR`:
+
+```sh
+export NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist
+nvm install node
+
+NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 4.2
+```
+
+To use a mirror of the io.js binaries, set `$NVM_IOJS_ORG_MIRROR`:
+
+```sh
+export NVM_IOJS_ORG_MIRROR=https://iojs.org/dist
+nvm install iojs-v1.0.3
+
+NVM_IOJS_ORG_MIRROR=https://iojs.org/dist nvm install iojs-v1.0.3
+```
+
+`nvm use` will not, by default, create a "current" symlink. Set `$NVM_SYMLINK_CURRENT` to "true" to enable this behavior, which is sometimes useful for IDEs. Note that using `nvm` in multiple shell tabs with this environment variable enabled can cause race conditions.
+
+### .nvmrc
+
+You can create a `.nvmrc` file containing a node version number (or any other string that `nvm` understands; see `nvm --help` for details) in the project root directory (or any parent directory).
+Afterwards, `nvm use`, `nvm install`, `nvm exec`, `nvm run`, and `nvm which` will use the version specified in the `.nvmrc` file if no version is supplied on the command line.
+
+For example, to make nvm default to the latest 5.9 release, the latest LTS version, or the latest node version for the current directory:
+
+```sh
+$ echo "5.9" > .nvmrc
+
+$ echo "lts/*" > .nvmrc # to default to the latest LTS version
+
+$ echo "node" > .nvmrc # to default to the latest version
+```
+
+[NB these examples assume a POSIX-compliant shell version of `echo`. If you use a Windows `cmd` development environment, eg the `.nvmrc` file is used to configure a remote Linux deployment, then keep in mind the `"`s will be copied leading to an invalid file. Remove them.]
+
+Then when you run nvm:
+
+```sh
+$ nvm use
+Found '/path/to/project/.nvmrc' with version <5.9>
+Now using node v5.9.1 (npm v3.7.3)
+```
+
+`nvm use` et. al. will traverse directory structure upwards from the current directory looking for the `.nvmrc` file. In other words, running `nvm use` et. al. in any subdirectory of a directory with an `.nvmrc` will result in that `.nvmrc` being utilized.
+
+The contents of a `.nvmrc` file **must** be the `<version>` (as described by `nvm --help`) followed by a newline. No trailing spaces are allowed, and the trailing newline is required.
+
+### Deeper Shell Integration
+
+You can use [`avn`](https://github.com/wbyoung/avn) to deeply integrate into your shell and automatically invoke `nvm` when changing directories. `avn` is **not** supported by the `nvm` maintainers. Please [report issues to the `avn` team](https://github.com/wbyoung/avn/issues/new).
+
+If you prefer a lighter-weight solution, the recipes below have been contributed by `nvm` users. They are **not** supported by the `nvm` maintainers. We are, however, accepting pull requests for more examples.
+
+#### bash
+
+##### Automatically call `nvm use`
+
+Put the following at the end of your `$HOME/.bashrc`:
+
+```bash
+cdnvm() {
+    command cd "$@";
+    nvm_path=$(nvm_find_up .nvmrc | tr -d '\n')
+
+    # If there are no .nvmrc file, use the default nvm version
+    if [[ ! $nvm_path = *[^[:space:]]* ]]; then
+
+        declare default_version;
+        default_version=$(nvm version default);
+
+        # If there is no default version, set it to `node`
+        # This will use the latest version on your machine
+        if [[ $default_version == "N/A" ]]; then
+            nvm alias default node;
+            default_version=$(nvm version default);
+        fi
+
+        # If the current version is not the default version, set it to use the default version
+        if [[ $(nvm current) != "$default_version" ]]; then
+            nvm use default;
+        fi
+
+        elif [[ -s $nvm_path/.nvmrc && -r $nvm_path/.nvmrc ]]; then
+        declare nvm_version
+        nvm_version=$(<"$nvm_path"/.nvmrc)
+
+        declare locally_resolved_nvm_version
+        # `nvm ls` will check all locally-available versions
+        # If there are multiple matching versions, take the latest one
+        # Remove the `->` and `*` characters and spaces
+        # `locally_resolved_nvm_version` will be `N/A` if no local versions are found
+        locally_resolved_nvm_version=$(nvm ls --no-colors "$nvm_version" | tail -1 | tr -d '\->*' | tr -d '[:space:]')
+
+        # If it is not already installed, install it
+        # `nvm install` will implicitly use the newly-installed version
+        if [[ "$locally_resolved_nvm_version" == "N/A" ]]; then
+            nvm install "$nvm_version";
+        elif [[ $(nvm current) != "$locally_resolved_nvm_version" ]]; then
+            nvm use "$nvm_version";
+        fi
+    fi
+}
+alias cd='cdnvm'
+cd "$PWD"
+```
+
+This alias would search 'up' from your current directory in order to detect a `.nvmrc` file. If it finds it, it will switch to that version; if not, it will use the default version.
+
+#### zsh
+
+##### Calling `nvm use` automatically in a directory with a `.nvmrc` file
+
+Put this into your `$HOME/.zshrc` to call `nvm use` automatically whenever you enter a directory that contains an
+`.nvmrc` file with a string telling nvm which node to `use`:
+
+```zsh
+# place this after nvm initialization!
+autoload -U add-zsh-hook
+load-nvmrc() {
+  local node_version="$(nvm version)"
+  local nvmrc_path="$(nvm_find_nvmrc)"
+
+  if [ -n "$nvmrc_path" ]; then
+    local nvmrc_node_version=$(nvm version "$(cat "${nvmrc_path}")")
+
+    if [ "$nvmrc_node_version" = "N/A" ]; then
+      nvm install
+    elif [ "$nvmrc_node_version" != "$node_version" ]; then
+      nvm use
+    fi
+  elif [ "$node_version" != "$(nvm version default)" ]; then
+    echo "Reverting to nvm default version"
+    nvm use default
+  fi
+}
+add-zsh-hook chpwd load-nvmrc
+load-nvmrc
+```
+
+#### fish
+
+##### Calling `nvm use` automatically in a directory with a `.nvmrc` file
+This requires that you have [bass](https://github.com/edc/bass) installed.
+```fish
+# ~/.config/fish/functions/nvm.fish
+function nvm
+  bass source ~/.nvm/nvm.sh --no-use ';' nvm $argv
+end
+
+# ~/.config/fish/functions/nvm_find_nvmrc.fish
+function nvm_find_nvmrc
+  bass source ~/.nvm/nvm.sh --no-use ';' nvm_find_nvmrc
+end
+
+# ~/.config/fish/functions/load_nvm.fish
+function load_nvm --on-variable="PWD"
+  set -l default_node_version (nvm version default)
+  set -l node_version (nvm version)
+  set -l nvmrc_path (nvm_find_nvmrc)
+  if test -n "$nvmrc_path"
+    set -l nvmrc_node_version (nvm version (cat $nvmrc_path))
+    if test "$nvmrc_node_version" = "N/A"
+      nvm install (cat $nvmrc_path)
+    else if test nvmrc_node_version != node_version
+      nvm use $nvmrc_node_version
+    end
+  else if test "$node_version" != "$default_node_version"
+    echo "Reverting to default Node version"
+    nvm use default
+  end
+end
+
+# ~/.config/fish/config.fish
+# You must call it on initialization or listening to directory switching won't work
+load_nvm
+```
+
+## Running Tests
+
+Tests are written in [Urchin]. Install Urchin (and other dependencies) like so:
+
+    npm install
+
+There are slow tests and fast tests. The slow tests do things like install node
+and check that the right versions are used. The fast tests fake this to test
+things like aliases and uninstalling. From the root of the nvm git repository,
+run the fast tests like this:
+
+    npm run test/fast
+
+Run the slow tests like this:
+
+    npm run test/slow
+
+Run all of the tests like this:
+
+    npm test
+
+Nota bene: Avoid running nvm while the tests are running.
+
+## Environment variables
+
+nvm exposes the following environment variables:
+
+- `NVM_DIR` - nvm's installation directory.
+- `NVM_BIN` - where node, npm, and global packages for the active version of node are installed.
+- `NVM_INC` - node's include file directory (useful for building C/C++ addons for node).
+- `NVM_CD_FLAGS` - used to maintain compatibility with zsh.
+- `NVM_RC_VERSION` - version from .nvmrc file if being used.
+
+Additionally, nvm modifies `PATH`, and, if present, `MANPATH` and `NODE_PATH` when changing versions.
+
+
+## Bash Completion
+
+To activate, you need to source `bash_completion`:
+
+```sh
+[[ -r $NVM_DIR/bash_completion ]] && \. $NVM_DIR/bash_completion
+```
+
+Put the above sourcing line just below the sourcing line for nvm in your profile (`.bashrc`, `.bash_profile`).
+
+### Usage
+
+nvm:
+> $ nvm <kbd>Tab</kbd>
+
+```
+alias               deactivate          install             list-remote         reinstall-packages  uninstall           version
+cache               exec                install-latest-npm  ls                  run                 unload              version-remote
+current             help                list                ls-remote           unalias             use                 which
+```
+
+nvm alias:
+> $ nvm alias <kbd>Tab</kbd>
+
+```
+default      iojs         lts/*        lts/argon    lts/boron    lts/carbon   lts/dubnium  lts/erbium   node         stable       unstable
+```
+
+> $ nvm alias my_alias <kbd>Tab</kbd>
+
+```
+v10.22.0       v12.18.3      v14.8.0
+```
+
+nvm use:
+> $ nvm use <kbd>Tab</kbd>
+
+```
+my_alias        default        v10.22.0       v12.18.3      v14.8.0
+```
+
+nvm uninstall:
+> $ nvm uninstall <kbd>Tab</kbd>
+
+```
+my_alias        default        v10.22.0       v12.18.3      v14.8.0
+```
+
+## Compatibility Issues
+
+`nvm` will encounter some issues if you have some non-default settings set. (see [#606](https://github.com/creationix/nvm/issues/606))
+The following are known to cause issues:
+
+Inside `~/.npmrc`:
+
+```sh
+prefix='some/path'
+```
+
+Environment Variables:
+
+```sh
+$NPM_CONFIG_PREFIX
+$PREFIX
+```
+
+Shell settings:
+
+```sh
+set -e
+```
+
+## Installing nvm on Alpine Linux
+
+In order to provide the best performance (and other optimisations), nvm will download and install pre-compiled binaries for Node (and npm) when you run `nvm install X`. The Node project compiles, tests and hosts/provides these pre-compiled binaries which are built for mainstream/traditional Linux distributions (such as Debian, Ubuntu, CentOS, RedHat et al).
+
+Alpine Linux, unlike mainstream/traditional Linux distributions, is based on [BusyBox](https://www.busybox.net/), a very compact (~5MB) Linux distribution. BusyBox (and thus Alpine Linux) uses a different C/C++ stack to most mainstream/traditional Linux distributions - [musl](https://www.musl-libc.org/). This makes binary programs built for such mainstream/traditional incompatible with Alpine Linux, thus we cannot simply `nvm install X` on Alpine Linux and expect the downloaded binary to run correctly - you'll likely see "...does not exist" errors if you try that.
+
+There is a `-s` flag for `nvm install` which requests nvm download Node source and compile it locally.
+
+If installing nvm on Alpine Linux *is* still what you want or need to do, you should be able to achieve this by running the following from you Alpine Linux shell:
+
+```sh
+apk add -U curl bash ca-certificates openssl ncurses coreutils python2 make gcc g++ libgcc linux-headers grep util-linux binutils findutils
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+```
+
+The Node project has some desire but no concrete plans (due to the overheads of building, testing and support) to offer Alpine-compatible binaries.
+
+As a potential alternative, @mhart (a Node contributor) has some [Docker images for Alpine Linux with Node and optionally, npm, pre-installed](https://github.com/mhart/alpine-node).
+
+<a id="removal"></a>
+## Uninstalling / Removal
+
+### Manual Uninstall
+
+To remove `nvm` manually, execute the following:
+
+```sh
+$ rm -rf "$NVM_DIR"
+```
+
+Edit `~/.bashrc` (or other shell resource config) and remove the lines below:
+
+```sh
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
+[[ -r $NVM_DIR/bash_completion ]] && \. $NVM_DIR/bash_completion
+```
+
+## Docker For Development Environment
+
+To make the development and testing work easier, we have a Dockerfile for development usage, which is based on Ubuntu 18.04 base image, prepared with essential and useful tools for `nvm` development, to build the docker image of the environment, run the docker command at the root of `nvm` repository:
+
+```sh
+$ docker build -t nvm-dev .
+```
+
+This will package your current nvm repository with our pre-defined development environment into a docker image named `nvm-dev`, once it's built with success, validate your image via `docker images`:
+
+```sh
+$ docker images
+
+REPOSITORY         TAG                 IMAGE ID            CREATED             SIZE
+nvm-dev            latest              9ca4c57a97d8        7 days ago          650 MB
+```
+
+If you got no error message, now you can easily involve in:
+
+```sh
+$ docker run -h nvm-dev -it nvm-dev
+
+nvm@nvm-dev:~/.nvm$
+```
+
+Please note that it'll take about 8 minutes to build the image and the image size would be about 650MB, so it's not suitable for production usage.
+
+For more information and documentation about docker, please refer to its official website:
+
+  - https://www.docker.com/
+  - https://docs.docker.com/
+
+## Problems
+
+  - If you try to install a node version and the installation fails, be sure to run `nvm cache clear` to delete cached node downloads, or you might get an error like the following:
+
+    curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.
+
+  - Where's my `sudo node`? Check out [#43](https://github.com/nvm-sh/nvm/issues/43)
+
+  - After the v0.8.6 release of node, nvm tries to install from binary packages. But in some systems, the official binary packages don't work due to incompatibility of shared libs. In such cases, use `-s` option to force install from source:
+
+```sh
+nvm install -s 0.8.6
+```
+
+  - If setting the `default` alias does not establish the node version in new shells (i.e. `nvm current` yields `system`), ensure that the system's node `PATH` is set before the `nvm.sh` source line in your shell profile (see [#658](https://github.com/nvm-sh/nvm/issues/658))
+
+## macOS Troubleshooting
+
+**nvm node version not found in vim shell**
+
+If you set node version to a version other than your system node version `nvm use 6.2.1` and open vim and run `:!node -v` you should see `v6.2.1` if you see your system version `v0.12.7`. You need to run:
+
+```shell
+sudo chmod ugo-x /usr/libexec/path_helper
+```
+
+More on this issue in [dotphiles/dotzsh](https://github.com/dotphiles/dotzsh#mac-os-x).
+
+**nvm is not compatible with the npm config "prefix" option**
+
+Some solutions for this issue can be found [here](https://github.com/nvm-sh/nvm/issues/1245)
+
+There is one more edge case causing this issue, and that's a **mismatch between the `$HOME` path and the user's home directory's actual name**.
+
+You have to make sure that the user directory name in `$HOME` and the user directory name you'd see from running `ls /Users/` **are capitalized the same way** ([See this issue](https://github.com/nvm-sh/nvm/issues/2261)).
+
+To change the user directory and/or account name follow the instructions [here](https://support.apple.com/en-us/HT201548)

+
+```shell

+Ignore insecure directories and continue [y] or abort compinit [n]? y
+```
+
+Homebrew causes insecure directories like `/usr/local/share/zsh/site-functions` and `/usr/local/share/zsh`. This is **not** an `nvm` problem - it is a homebrew problem. Refer [here](https://github.com/zsh-users/zsh-completions/issues/680) for some solutions related to the issue.
+
+**Macs with M1 chip**
+
+_January 2021:_ there are no pre-compiled NodeJS binaries for versions prior to 15.x for Apple's new M1 chip (arm64 architecture).
+
+Some issues you may encounter:
+
+- using `nvm` to install, say, `v14.15.4`:
+  - the C code compiles successfully
+  - but crashes with an out of memory error when used
+  - increasing the memory available to node still produces the out of memory errors:
+    ```sh
+    $ NODE_OPTIONS="--max-old-space-size=4096" ./node_modules/.bin/your_node_package
+    ```
+- when using `nvm` to install some versions, the compilation fails
+
+One solution to this issue is to change the architecture of your shell from arm64 to x86.
+
+Let's assume that:
+- you already have versions `12.20.1` and `14.15.4` installed using `nvm`
+- the current version in use is `14.15.4`
+- you are using the `zsh` shell
+- you have Rosetta 2 installed (macOS prompts you to install Rosetta 2 the first time you open a Intel-only non-command-line application, or you may install Rosetta 2 from the command line with `softwareupdate --install-rosetta`)
+
+```sh
+# Check what version you're running:
+$ node --version
+v14.15.4
+# Check architecture of the `node` binary:
+$ node -p process.arch
+arm64
+# This confirms that the arch is for the M1 chip, which is causing the problems.
+# So we need to uninstall it.
+# We can't uninstall the version we are currently using, so switch to another version:

+# nvm Road Map
+
+This is a list of the primary features planned for `nvm`:
+
+- [x] Rewriting installation code paths to support installing `io.js` and `node` `v4+` [from source](https://github.com/nvm-sh/nvm/issues/1188).
+  - This will include [reusing previously downloaded tarballs](https://github.com/nvm-sh/nvm/issues/1193) that match checksums, which is a nice performance and bandwidth bonus.
+- [ ] Adding opt-in environment variable support to list, download, and install `node` [release candidates](https://github.com/nvm-sh/nvm/issues/779), and [nightly builds](https://github.com/nvm-sh/nvm/issues/1053).
+- [ ] [`nvm update`](https://github.com/nvm-sh/nvm/issues/400): the ability to autoupdate `nvm` itself
+- [ ] [v1.0.0](https://github.com/nvm-sh/nvm/milestone/1), including updating the [nvm on npm](https://github.com/nvm-sh/nvm/issues/304) to auto-install nvm properly
