-This action sets by node environment for use in actions by:
+This action provides the following functionality for GitHub Actions users:
 
-- optionally downloading and caching a version of node - npm by version spec and add to PATH
-- registering problem matchers for error output
-- configuring authentication for GPR or npm
+- Optionally downloading and caching distribution of the requested Node.js version, and adding it to the PATH
+- Optionally caching npm/yarn/pnpm dependencies
+- Registering problem matchers for error output
+- Configuring authentication for GPR or npm
 
-# v2-beta
-
-A beta release which adds reliability for pulling node distributions from a cache of node releases is available by referencing the `v2-beta` tag.
-
-```yaml
-steps:
-- uses: actions/checkout@v2
-- uses: actions/setup-node@v2-beta
-  with:
-    node-version: '12'
-```
-
-It will first check the local cache for a semver match.  The hosted images have been updated with the latest of each LTS from v8, v10, v12, and v14. `self-hosted` machines will benefit from the cache as well only downloading once.  It will pull LTS versions from `main` branch of [node-versions](https://github.com/actions/node-versions/blob/main/versions-manifest.json) repository and on miss or failure, it will fall back to the previous behavior of download directly from [node dist](https://nodejs.org/dist/).
-
-The `node-version` input is optional.  If not supplied, node which is in your PATH will be used.  However, this action will still register problem matchers and support auth features.  So setting up the node environment is still a valid scenario without downloading and caching versions.

+    # Version Spec of the version to use in SemVer notation.
+    # It also emits such aliases as lts, latest, nightly and canary builds

+    node-version: ''
+
+    # File containing the version Spec of the version to use.  Examples: .nvmrc, .node-version, .tool-versions.
+    # If node-version and node-version-file are both provided the action will use version from node-version. 
+    node-version-file: ''
+
+    # Set this option if you want the action to check for the latest available version 
+    # that satisfies the version spec.
+    # It will only get affect for lts Nodejs versions (12.x, >=10.15.0, lts/Hydrogen). 
+    # Default: false
+    check-latest: false
+
+    # Target architecture for Node to use. Examples: x86, x64. Will use system architecture by default.
+    # Default: ''. The action use system architecture by default 
+    architecture: ''
+
+    # Used to pull node distributions from https://github.com/actions/node-versions. 
+    # Since there's a default, this is typically not supplied by the user. 
+    # When running this action on github.com, the default value is sufficient. 
+    # When running on GHES, you can pass a personal access token for github.com if you are experiencing rate limiting.
+    #
+    # We recommend using a service account with the least permissions necessary. Also
+    # when generating a new PAT, select the least scopes necessary.
+    #
+    # [Learn more about creating and using encrypted secrets](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets)
+    #
+    # Default: ${{ github.server_url == 'https://github.com' && github.token || '' }}
+    token: ''
+
+    # Used to specify a package manager for caching in the default directory. Supported values: npm, yarn, pnpm.
+    # Package manager should be pre-installed
+    # Default: ''
+    cache: ''
+
+    # Used to specify the path to a dependency file: package-lock.json, yarn.lock, etc. 
+    # It will generate hash from the target file for primary key. It works only If cache is specified.  
+    # Supports wildcards or a list of file names for caching multiple dependencies.
+    # Default: ''
+    cache-dependency-path: ''
+
+    # Optional registry to set up for auth. Will set the registry in a project level .npmrc and .yarnrc file, 
+    # and set up auth to read in from env.NODE_AUTH_TOKEN.
+    # Default: ''

 steps:
-- uses: actions/checkout@v2
-- uses: actions/setup-node@v1
+- uses: actions/checkout@v3
+- uses: actions/setup-node@v3

-Check latest version:  
-> In basic example, without `check-latest` flag, the action tries to resolve version from local cache firstly and download only if it is not found. Local cache on image is updated with a couple of weeks latency.  
-`check-latest` flag forces the action to check if the cached version is the latest one. It reduces latency significantly but it is much more likely to incur version downloading.
+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 Runner Images](https://github.com/actions/runner-images).
+
+### Supported version syntax
+
+The `node-version` input supports the Semantic Versioning Specification, for more detailed examples please refer to [the semver package documentation](https://github.com/npm/node-semver).
+
+Examples:
+
+ - 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`
+
+**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.
+
+`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:**

-Architecture:
+## Using `setup-node` on GHES
 
-You can use any of the [supported operating systems](https://docs.github.com/en/actions/reference/virtual-environments-for-github-hosted-runners), and the compatible `architecture` can be selected using `architecture`. Values are `x86`, `x64`, `arm64`, `armv6l`, `armv7l`, `ppc64le`, `s390x` (not all of the architectures are available on all platforms).
+`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.
 
-When using `architecture`, `node-version` must be provided as well.
-```yaml
-jobs:
-  build:
-    runs-on: windows-latest
-    name: Node sample
-    steps:
-      - uses: actions/checkout@v2
-      - uses: actions/setup-node@v1
-        with:
-          node-version: '12'
-          architecture: 'x64' # optional, x64 or x86. If not specified, x64 will be used by default
-      - run: npm install
-      - run: npm test
-```
-
-Multiple Operating Systems and Architectures:
+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
-jobs:
-  build:
-    runs-on: ${{ matrix.os }}
-    strategy:
-      matrix:
-        os:
-          - ubuntu-latest
-          - macos-latest
-          - windows-latest
-        node_version:
-          - 10
-          - 12
-          - 14
-        architecture:
-          - x64
-        # an extra windows-x86 run:
-        include:
-          - os: windows-2016
