 - 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/checkout@v3
-- uses: actions/setup-node@v2
+- uses: actions/setup-node@v3
   with:
-    node-version: '14'
+    node-version: 16
-- run: npm install
+- 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).
 
-#### Supported version syntax
+### Supported version syntax
-The `node-version` input supports the following syntax:
 
-major versions: `12`, `14`, `16`  
+The `node-version` input supports the Semantic Versioning Specification, for more detailed examples please refer to the [documentation](https://github.com/npm/node-semver).
-more specific versions: `10.15`, `14.2.0`, `16.3.0`  
-nvm lts syntax: `lts/erbium`, `lts/fermium`, `lts/*`  
 
-## 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 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/virtual-environments/blob/main/images/linux/Ubuntu2004-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:**
+

+    node-version: 16
     cache: 'npm'
-- run: npm install
+- run: npm ci
 - run: npm test
 ```
 
 **Caching npm dependencies in monorepos:**
+

-# 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)
