 - Registering problem matchers for error output
 - Configuring authentication for GPR or npm
 
-# Usage
+## Usage
 
 See [action.yml](action.yml)
 
 **Basic:**
+
 ```yaml
 steps:
-- uses: actions/checkout@v2
-- uses: actions/setup-node@v2
+- uses: actions/checkout@v3
+- uses: actions/setup-node@v3
   with:
-    node-version: '14'
-- run: npm install
+    node-version: 16
+- run: npm ci
 - run: npm test
 ```
 
-The `node-version` input is optional. If not supplied, the node version from PATH will be used. However, it is recommended to always specify Node.js version and don't rely on the system one.  
+The `node-version` input is optional. If not supplied, the node version from PATH will be used. However, it is recommended to always specify Node.js version and don't rely on the system one.
 
 The action will first check the local cache for a semver match. If unable to find a specific version in the cache, the action will attempt to download a version of Node.js. It will pull LTS versions from [node-versions releases](https://github.com/actions/node-versions/releases) and on miss or failure will fall back to the previous behavior of downloading directly from [node dist](https://nodejs.org/dist/).
 
-For information regarding locally cached versions of Node.js on GitHub hosted runners, check out [GitHub Actions Virtual Environments](https://github.com/actions/virtual-environments).
+For information regarding locally cached versions of Node.js on GitHub hosted runners, check out [GitHub Actions Runner Images](https://github.com/actions/runner-images).
 
-#### Supported version syntax
-The `node-version` input supports the following syntax:
+### Supported version syntax
 
-major versions: `12`, `14`, `16`  
-more specific versions: `10.15`, `14.2.0`, `16.3.0`  
-nvm lts syntax: `lts/erbium`, `lts/fermium`, `lts/*`  
+The `node-version` input supports the Semantic Versioning Specification, for more detailed examples please refer to the [documentation](https://github.com/npm/node-semver).
 
-## Caching packages dependencies
+Examples:
 
-The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under the hood for caching dependencies but requires less configuration settings. Supported package managers are `npm`, `yarn`, `pnpm` (v6.10+). The `cache` input is optional, and caching is turned off by default.
+ - Major versions: `14`, `16`, `18`
+ - More specific versions: `10.15`, `16.15.1` , `18.4.0`
+ - NVM LTS syntax: `lts/erbium`, `lts/fermium`, `lts/*`, `lts/-n`
+ - Latest release: `*` or `latest`/`current`/`node`
 
-The action defaults to search for the dependency file (`package-lock.json` or `yarn.lock`) in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.
+**Note:** Like the other values, `*` will get the latest [locally-cached Node.js version](https://github.com/actions/runner-images/blob/main/images/linux/Ubuntu2204-Readme.md#nodejs), or the latest version from [actions/node-versions](https://github.com/actions/node-versions/blob/main/versions-manifest.json), depending on the [`check-latest`](docs/advanced-usage.md#check-latest-version) input.
 
-See the examples of using cache for `yarn` / `pnpm` and  `cache-dependency-path` input in the [Advanced usage](docs/advanced-usage.md#caching-packages-dependencies) guide.
+`current`/`latest`/`node` always resolve to the latest [dist version](https://nodejs.org/dist/index.json).
+That version is then downloaded from actions/node-versions if possible, or directly from Node.js if not.
+Since it will not be cached always, there is possibility of hitting rate limit when downloading from dist
+
+### Checking in lockfiles
+
+It's **always** recommended to commit the lockfile of your package manager for security and performance reasons. For more information consult the "Working with lockfiles" section of the [Advanced usage](docs/advanced-usage.md#working-with-lockfiles) guide.
+
+## Caching global packages data
+
+The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under the hood for caching global packages data but requires less configuration settings. Supported package managers are `npm`, `yarn`, `pnpm` (v6.10+). The `cache` input is optional, and caching is turned off by default.
+
+The action defaults to search for the dependency file (`package-lock.json`, `npm-shrinkwrap.json` or `yarn.lock`) in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.
+
+**Note:** The action does not cache `node_modules`
+
+See the examples of using cache for `yarn`/`pnpm` and `cache-dependency-path` input in the [Advanced usage](docs/advanced-usage.md#caching-packages-data) guide.
 
 **Caching npm dependencies:**
+
 ```yaml
 steps:
-- uses: actions/checkout@v2
-- uses: actions/setup-node@v2
+- uses: actions/checkout@v3
+- uses: actions/setup-node@v3
   with:
-    node-version: '14'
+    node-version: 16
     cache: 'npm'
-- run: npm install
+- run: npm ci
 - run: npm test
 ```
 
 **Caching npm dependencies in monorepos:**
+
 ```yaml
 steps:
-- uses: actions/checkout@v2

+## Using `setup-node` on GHES
+
+`setup-node` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading Nodejs distributions, `setup-node` downloads distributions from [`actions/node-versions`](https://github.com/actions/node-versions) on github.com (outside of the appliance). These calls to `actions/node-versions` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If more requests are made within the time frame, then you will start to see rate-limit errors during downloading that looks like: `##[error]API rate limit exceeded for...`. After that error the action will try to download versions directly from the official site, but it also can have rate limit so it's better to put token.
+
+To get a higher rate limit, you can [generate a personal access token on github.com](https://github.com/settings/tokens/new) and pass it as the `token` input for the action:
+
+```yaml
+uses: actions/setup-node@v3
+with:
+  token: ${{ secrets.GH_DOTCOM_TOKEN }}
+  node-version: 16
+```
+
+If the runner is not able to access github.com, any Nodejs versions requested during a workflow run must come from the runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)" for more information.

-# Advanced usage
+## Working with lockfiles
+
+All supported package managers recommend that you **always** commit the lockfile, although implementations vary doing so generally provides the following benefits:
+
+- Enables faster installation for CI and production environments, due to being able to skip package resolution.
+- Describes a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.
+- Provides a facility for users to "time-travel" to previous states of `node_modules` without having to commit the directory itself.
+- Facilitates greater visibility of tree changes through readable source control diffs.
+
+In order to get the most out of using your lockfile on continuous integration follow the conventions outlined below for your respective package manager.
+
+### NPM
+
+Ensure that `package-lock.json` is always committed, use `npm ci` instead of `npm install` when installing packages.
+
+**See also:**
+- [Documentation of `package-lock.json`](https://docs.npmjs.com/cli/v8/configuring-npm/package-lock-json)
+- [Documentation of `npm ci`](https://docs.npmjs.com/cli/v8/commands/npm-ci)
+
+### Yarn
+
+To ensure that `yarn.lock` is always committed, use `yarn install --immutable` when installing packages.
+
+**See also:**
+- [Documentation of `yarn.lock`](https://classic.yarnpkg.com/en/docs/yarn-lock)
+- [Documentation of `--frozen-lockfile` option](https://classic.yarnpkg.com/en/docs/cli/install#toc-yarn-install-frozen-lockfile)
+- [QA - Should lockfiles be committed to the repoistory?](https://yarnpkg.com/getting-started/qa/#should-lockfiles-be-committed-to-the-repository)
+- [Documentation of `yarn install`](https://yarnpkg.com/cli/install)
+
+### PNPM
+
+Ensure that `pnpm-lock.yaml` is always committed, when on CI pass `--frozen-lockfile` to `pnpm install` when installing packages.
+
+**See also:**
+- [Working with Git - Lockfiles](https://pnpm.io/git#lockfiles)

 ## Node version file
-  
-The `node-version-file` input accepts a path to a file containing the version of Node.js to be used by a project, for example `.nvmrc` or `.node-version`. If both the `node-version` and the `node-version-file` inputs are provided then the `node-version` input is used.

+## Caching packages data
 The action follows [actions/cache](https://github.com/actions/cache/blob/main/examples.md#node---npm) guidelines, and caches global cache on the machine instead of `node_modules`, so cache can be reused between different Node.js versions.

+Yarn2 ignores both .npmrc and .yarnrc files created by the action, so before installing dependencies from the private repo it is necessary either to create or to modify existing yarnrc.yml file with `yarn config set` commands.
+

+
+```yaml

+  env:
+    NPM_AUTH_TOKEN: ${{ secrets.YARN_TOKEN }}
+- name: Install dependencies
+  run: yarn install --immutable
+```
+NOTE: As per https://github.com/actions/setup-node/issues/49 you cannot use `secrets.GITHUB_TOKEN` to access private GitHub Packages within the same organisation but in a different repository.
+
+### always-auth input
+The always-auth input sets `always-auth=true` in .npmrc file. With this option set [npm](https://docs.npmjs.com/cli/v6/using-npm/config#always-auth)/yarn sends the authentication credentials when making a request to the registries.

 # Contributors
 
-### Checkin
+Thank you for contributing!
 
-- Do checkin source (src)
-- Do checkin build output (lib)
-- Do checkin runtime node_modules
-- Do not checkin devDependency node_modules (husky can help see below)
+We have prepared a short guide so that the process of making your contribution is as simple and clear as possible. Please check it out before you contribute!
 
-### devDependencies
+## How can I contribute...
 
-In order to handle correctly checking in node_modules without devDependencies, we run [Husky](https://github.com/typicode/husky) before each commit.
-This step ensures that formatting and checkin rules are followed and that devDependencies are excluded. To make sure Husky runs correctly, please use the following workflow:
+* [Contribute Documentation:green_book:](#contribute-documentation)
 
-```
-npm install                                 # installs all devDependencies including Husky
-git add abc.ext                             # Add the files you've changed. This should include files in src, lib, and node_modules (see above)
-git commit -m "Informative commit message"  # Commit. This will run Husky
-```
+* [Contribute Code :computer:](#contribute-code)
 
-During the commit step, Husky will take care of formatting all files with [Prettier](https://github.com/prettier/prettier) as well as pruning out devDependencies using `npm prune --production`.
-It will also make sure these changes are appropriately included in your commit (no further work is needed)
+* [Provide Support on Issues:pencil:](#provide-support-on-issues)

+* [Review Pull Requests:mag:](#review-pull-requests)
+
+## Contribute documentation
+
+Documentation is a super important, critical part of this project. Docs are how we keep track of what we're doing, how, and why. It's how we stay on the same page about our policies and how we tell others everything they need to be able to use this project or contribute to it. 
+
+Documentation contributions of any size are welcome! Feel free to contribute even if you're just rewording a sentence to be more clear, or fixing a spelling mistake!
+
+**How to contribute:**
+
+Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a convenient way of commenting and amending the proposed changes.
+
+- Please check that no one else has already created a pull request with these or similar changes
+- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request 
+- Make sure your changes are formatted properly and consistently with the rest of the documentation
+- Re-read what you wrote, and run a spellchecker on it to make sure you didn't miss anything
+- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
+- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
+
+**Once you've filed the pull request:**
+
+- Maintainers will review your pull request
+- If a maintainer requests changes, first of all, try to think about this request critically and only after that implement and request another review
+- If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action and updating the major tag
+> Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:
+
+## Contribute code
+
+We like code commits a lot! They're super handy, and they keep the project going and doing the work it needs to do to be useful to others.
+
+Code contributions of just about any size are acceptable!
+
+The main difference between code contributions and documentation contributions is that contributing code requires the inclusion of relevant tests for the code being added or changed. Contributions without accompanying tests will be held off until a test is added unless the maintainers consider the specific tests to be either impossible or way too much of a burden for such a contribution.
+
+**How to contribute:**
+
+Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a convenient way of commenting and amending the proposed changes.
+
+- Please check that no one else has already created a pull request with these or similar changes
+- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request
+-  **Run `pre-checkin` script to format, build and test changes**
+- Make sure your changes are well formatted and that all tests are passing
+- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
+- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
+
+**Learn more about how to work with the repository:**
+
+- To implement new features or fix bugs, you need to make changes to the `.ts` files, which are located in the `src` folder
+- To comply with the code style, **you need to run the `format` script**
+- To transpile source code to `javascript` we use [NCC](https://github.com/vercel/ncc). **It is very important to run the `build` script after making changes**, otherwise your changes will not get into the final `javascript` build
+- You can also start formatting, building code, and testing with a single `pre-checkin` command
+
+**Learn more about how to implement tests:**
+
+Adding or changing tests is an integral part of making a change to the code. 
+Unit tests are in the `__tests__` folder, and end-to-end tests are in the `workflows` folder, particularly in the [versions.yml](https://github.com/actions/setup-node/blob/main/.github/workflows/versions.yml) and [e2e-cache.yml](https://github.com/actions/setup-node/blob/main/.github/workflows/e2e-cache.yml) files.
+
+- The contributor can add various types of tests (like unit tests or end-to-end tests), which, in his opinion, will be necessary and sufficient for testing new or changed functionality
+- Tests should cover a successful execution, as well as some edge cases and possible errors
+- As already mentioned, pull requests without tests will be considered more carefully by maintainers. If you are sure that in this situation the tests are not needed or cannot be implemented with a commensurate effort - please add this clarification message to your pull request
+
+**Once you've filed the pull request:**
+
+- CI will start automatically with some checks. Wait until the end of the execution and make sure that all checks passed successfully. If some checks fail, you can open them one by one, try to find the reason for failing and make changes to your code to resolve the problem
+- Maintainers will review your pull request
+- If a maintainer requests changes, first of all, try to think about his request critically and only after that implement and request another review
+- If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action and updating the major tag
+> Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:
+
+## Provide support on issues
+
+Helping out other users with their questions is an awesome way of contributing to any community. It's not uncommon for most of the issues on open source projects to be support-related questions by users trying to understand something they ran into or find their way around a known bug.
+
+**To help other folks out with their questions:**
+
+- Go to the [issue tracker](https://github.com/actions/setup-node/issues)
+- Read through the list until you find something that you're familiar enough with to answer to
+- Respond to the issue with whatever details are needed to clarify the question, or get more details about what's going on
+- Once the discussion wraps up and things are clarified, ask the original issue filer (or a maintainer) to close it for you
+ 
+*Some notes on picking up support issues:*
+
+- Avoid responding to issues you don't know you can answer accurately
+- Try to refer to past issues with accepted answers as much as possible. Link to them from your replies
+- Be kind and patient with users. Often, folks who have run into confusing things might be upset or impatient. This is natural. If you feel uncomfortable in conversation with them, it's better to stay away or withdraw from the issue.
+
+ > If some user is violating our code of conduct [standards](https://github.com/actions/setup-node/blob/main/CODE_OF_CONDUCT.md#our-standards), refer to the [Enforcement](https://github.com/actions/setup-node/blob/main/CODE_OF_CONDUCT.md#enforcement) section of the Code of Conduct to resolve the conflict
+ 
+
+## Review pull requests
+ 
+
+Another great way to contribute is to review pull request. Please, be extra kind: people who submit code/doc contributions are putting themselves in a pretty vulnerable position, and have put time and care into what they've done (even if that's not obvious to you!) Please, always respond with respect, and be understanding, but don't feel like you need to sacrifice your standards for their sake, either.
+ 
+**How to review:**
+
+- Go to the [pull requests](https://github.com/actions/setup-node/pulls)
+- Make sure you're familiar with the code or documentation is updated, unless it's a minor change (spellchecking, minor formatting, etc.)
+- Review changes using the GitHub functionality. You can ask a clarifying question, point out an error or suggest an alternative. 
+> Note: You may ask for minor changes - "nitpicks", but consider whether they are real blockers to merging or not
+- Submit your review, which may include comments, an approval, or a changes request
