+## OpenSSF CII Best Practices
+
+[![CII Best Practices](https://bestpractices.coreinfrastructure.org/projects/684/badge)](https://bestpractices.coreinfrastructure.org/projects/684)
+
+There are three “tiers”: passing, silver, and gold.
+
+### Passing
+We meet 100% of the “passing” criteria.
+
+### Silver
+We meet 95% of the “silver” criteria. The gaps are as follows:
+  - we do not have a DCO or a CLA process for contributions.
+  - because we only have one maintainer, the project has no way to continue if that maintainer stops being active.
+  - we do not currently document “what the user can and cannot expect in terms of security” for our project. This is planned to be completed in 2023.
+
+### Gold
+We meet 65% of the “gold” criteria. The gaps are as follows:
+  - we do not yet have the “silver” badge; see all the gaps above.
+  - We do not include a copyright or license statement in each source file. Efforts are underway to change this archaic practice into a suggestion instead of a hard requirement.

+# Code of Conduct
+
+`nvm`, as a member project of the OpenJS Foundation, uses [Contributor Covenant v2.1](https://www.contributor-covenant.org/version/2/1/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/2/1)
+
+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/HEAD/CODE_OF_CONDUCT.md).
+
+---
+
+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders 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, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at [@ljharb](ljharb@gmail.com).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.
+
+## Attribution

-Thanks for contributing to `nvm`!
+# Contributing
 
-We love pull requests, they're our favorite.
+:+1::tada: First off, thanks for taking the time to contribute to `nvm`! :tada::+1:
+
+We love pull requests and issues, they're our favorite.
+
+The following is a set of guidelines for contributing to `nvm` managed by [@LJHarb](https://github.com/ljharb), which is hosted on GitHub. These are mostly guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.
 
 However, before submitting, please review the following:
 
- - Please include tests. Changes with tests will be merged very quickly.
- - Please manually confirm that your changes work in `bash`, `sh`/`dash`, `ksh`, and `zsh`. Fast tests do run in these shells, but it's nice to manually verify also.
- - Please maintain consistent whitespace - 2-space indentation, trailing newlines in all files, etc.
- - Any time you make a change to your PR, please rebase freshly on top of master. Nobody likes merge commits.
+# How Can I Contribute?
 
-Even if you don't have all of these items covered, please still feel free to submit a PR! Someone else may be inspired and volunteer to complete it for you.
+There are lots of ways to get involved. Here are some suggestions of things we'd love some help with.
 
-Thanks again!
+## Resolving existing issues
 
+You can consider helping out with issues already requiring attention - look for a "help wanted" label.
+
+### How Do I Submit a (Good) Bug Report? :bug:
+
+Explain the problem and include additional details to help maintainers reproduce the problem:
+
+* **Use a clear and descriptive title** for the issue to identify the problem.
+
+* **Describe the exact steps which reproduce the problem** in as many details as possible. For example, start by explaining which command exactly you used in the terminal. When listing steps, **don't just say what you did, but explain how you did it**. For example, if you moved the cursor to the end of a line, explain if you used the mouse, or a keyboard shortcut or a command, and if so which one?
+* **Provide specific examples to demonstrate the steps**. Include links to files or Github projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
+* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
+* **Explain which behavior you expected to see instead and why.**
+* **Provide as much context as possible** in order to help others verify and ultimately fix the issue. This includes giving us as much details as possible about your environment, so we can more easily confirm the problem.
+
+## Documentation
+
+We are happy to welcome contributions from anyone willing to improve documentation by adding missing information or making it more consistent and coherent.
+
+# Dev Environment
+
+Please refer to the [README](README.md) for complete instructions how to install, update, as well as troubleshoot `nvm` in your environment depending on your Operating System.

+  - Please maintain consistent whitespace - 2-space indentation, trailing newlines in all files, etc.
+  - Any time you make a change to your PR, please rebase freshly on top of the default branch. Nobody likes merge commits.
+
+Even if you don't have all of these items covered, please still feel free to submit a PR/issue! Someone else may be inspired and volunteer to complete it for you.
+
+#### How to create a pull request
+
+Create a new branch
+
+```
+git checkout -b issue1234
+```
+
+Commit the changes to your branch, including a coherent commit message that follows our [standards](#commit-messages)
+
+```
+git commit -a
+```
+
+Before sending the pull request, make sure your code is running on the latest available code by rebasing onto the upstream source
+
+```
+git fetch upstream
+git rebase upstream/main
+```
+
+Verify your changes
+
+```
+npm test
+```
+
+Push your changes
+
+```
+git push origin issue1234

+# `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 4.3: Other Project Roles
+
+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.
-
-### Install script
-
-To install you could use the [install script][2] using cURL:
-
-    curl https://raw.githubusercontent.com/creationix/nvm/v0.8.0/install.sh | sh
-
-or Wget:
-
-    wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.8.0/install.sh | sh
-
-<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 `NVM_PROFILE` variables. Eg: `curl ... | NVM_DIR=/usr/local/nvm sh` 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:
-
-    git clone https://github.com/creationix/nvm.git ~/.nvm
-
-To activate nvm, you need to source it from your shell:
-
-    source ~/.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`, and `nvm run` will all respect an `.nvmrc` file.
-
-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
-
-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 0.10
-
-To use a mirror of the node binaries, set `$NVM_NODEJS_ORG_MIRROR`:
-
-    export NVM_NODEJS_ORG_MIRROR=http://nodejs.org/dist
-    nvm install 0.10
-
-    NVM_NODEJS_ORG_MIRROR=http://nodejs.org/dist nvm install 0.10
-

-
-## 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          copy-packages  help           list           run            uninstall      version
-	clear-cache    deactivate     install        ls             unalias        use
-
-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
-
-## 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'? Checkout 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

+# 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
