-# Checkout V2 beta
+This action checks out your repository to `$GITHUB_WORKSPACE`, so that your workflow can access the contents of your repository.
 
-This action checks-out your repository under `$GITHUB_WORKSPACE`, so your workflow can access it.
+By default, this is equivalent to running `git fetch` and `git checkout $GITHUB_SHA`, so that you'll always have your repo contents at the version that triggered the workflow.
-
+See [here](https://help.github.com/en/articles/events-that-trigger-workflows) to learn what `$GITHUB_SHA` is for different kinds of events.
-By default, the repository that triggered the workflow is checked-out, for the ref/SHA that triggered the event.
-
-Refer [here](https://help.github.com/en/articles/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.

 # Usage
 
-<!-- start usage -->
+See [action.yml](action.yml)
+
+Basic:
+
 ```yaml
-- uses: actions/checkout@v2-beta
+steps:
+- uses: actions/checkout@master
+- uses: actions/setup-node@master
   with:
-    # Repository name with owner. For example, actions/checkout
+    node-version: 10.x 
-    # Default: ${{ github.repository }}
+- run: npm install
-    repository: ''
+- run: npm test
-
-    # Ref to checkout (SHA, branch, tag). For the repository that triggered the
-    # workflow, defaults to the ref/SHA for the event. Otherwise defaults to master.
-    ref: ''
-
-    # Access token for clone repository
-    # Default: ${{ github.token }}
-    token: ''
-
-    # Relative path under $GITHUB_WORKSPACE to place the repository
-    path: ''
-
-    # Whether to execute `git clean -ffdx && git reset --hard HEAD` before fetching
-    # Default: true
-    clean: ''
-
-    # Number of commits to fetch. 0 indicates all history.
-    # Default: 1
-    fetch-depth: ''
-
-    # Whether to download Git-LFS files
-    # Default: false
-    lfs: ''
 ```
-<!-- end usage -->
 
-## Checkout a different branch
+By default, the branch or tag ref that triggered the workflow will be checked out. If you wish to check out a different branch, specify that using `with.ref`:
 
 ```yaml
-- uses: actions/checkout@preview
+- uses: actions/checkout@master
   with:
     ref: some-branch
 ```
 
-## Checkout a different, private repository
+For more details, see [Contexts and expression syntax for GitHub Actions](https://help.github.com/en/articles/contexts-and-expression-syntax-for-github-actions)
-
-```yaml
-- uses: actions/checkout@preview
-  with:
-    repository: myAccount/myRepository
-    ref: refs/heads/master
-    token: ${{ secrets.GitHub_PAT }} # `GitHub_PAT` is a secret that contains your PAT
-```
-> - `${{ github.token }}` is scoped to the current repository, so if you want to checkout another repository that is private you will need to provide your own [PAT](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line).
