 # Action Template
 
-GitHub action to echo "Hello World"
+Yyarn Install composite action for yarn 3/4+ and "nodeLinker: node-modules"
 
-Template repository for reusable GitHub actions
-
-You can use this guide to figure out how to update your application using the template: [Creating a new repository from a template](https://amuniversal.atlassian.net/wiki/spaces/TD/pages/3419832336/Creating+a+New+GitHub+Repository#Creating-a-new-repository-from-a-template)
+Reference: https://gist.github.com/belgattitude/042f9caf10d029badbde6cf9d43e400a
 
 ## Getting Started
 
 ```bash
-git clone https://github.com/Andrews-McMeel-Universal/action_template
+git clone https://github.com/Andrews-McMeel-Universal/cache-yarn-install
 ```
 
 ## Installation
 
-To make `action_template` a part of your workflow, just add a step to one of your workflows in your `.github/workflows/` directory in your GitHub repository.
+To make `cache-yarn-install` a part of your workflow, just add a step to one of your workflows in your `.github/workflows/` directory in your GitHub repository.
+
+> Requirement: @setup/node should be run before
+
+Example:
+```YAML
+- name: Cache Yarn Install
+  uses: Andrews-McMeel-Universal/cache-yarn-install@v1
+  with:
+    enable-corepack: false
+    cwd: ${{ github.workspace }}/apps/my-app
+    cache-prefix: add cache key prefix
+    cache-node-modules: false
+    cache-install-state: false
+```
 
 ## Options
 
 | Variable | Description       | Required | `[Default]`     |
 | -------- | ----------------- | :------: | --------------- |
-| `input`  | Input Description |    x     | `Default Value` |
+| `cwd`  | Changes node's process.cwd() if the project is not located on the root. Default to process.cwd() |         | `.` |
+| `cache-prefix`  | Add a specific cache-prefix |         | `'default'` |
+| `cache-npm-cache`  | Cache npm global cache folder often used by node-gyp, prebuild binaries (invalidated on lock/os/node-version) |         | `'true'` |
+| `cache-node-modules`  | Cache node_modules, might speed up link step (invalidated lock/os/node-version/branch) |         | `'false'` |
+| `cache-install-state`  | Cache yarn install state, might speed up resolution step when node-modules cache is activated (invalidated lock/os/node-version/branch) |         | `'false'` |
+| `enable-corepack`  | Enable corepack |        | `'true'` |
