-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 $GITHUB_SHA`, so that you'll always have your repo contents at the version that triggered the workflow.
-See [here](https://help.git.teamtekk.it/en/articles/events-that-trigger-workflows) to learn what `$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

-See [action.yml](action.yml)
-
-Basic:
-
+<!-- start usage -->
 ```yaml
-steps:
- uses: actions/checkout@v1
- uses: actions/setup-node@v1
+- uses: actions/checkout@v2-beta
  with:
-    node-version: 10.x 
- run: npm install
- run: npm test
+    # Repository name with owner. For example, actions/checkout
+    # Default: ${{ github.repository }}
+    repository: ''
+
+    # The branch, tag or SHA to checkout. When checking out the repository that
+    # triggered a workflow, this defaults to the reference or SHA for that event.
+    # Otherwise, defaults to `master`.
+    ref: ''
+
+    # Auth token used to fetch the repository. The token is stored in the local git
+    # config, which enables your scripts to run authenticated git commands. The
+    # post-job step removes the token from the git config.
+    # Default: ${{ github.token }}
+    token: ''
+
+    # Whether to persist the token in the git config
+    # Default: true
+    persist-credentials: ''
+
+    # 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 -->

-By default, the branch or tag ref that triggered the workflow will be checked out, `${{ github.token }}` will be used for any Git server authentication. If you wish to check out a different branch, a different repository or use different token to checkout, specify that using `with.ref`, `with.repository` and `with.token`:
+## Checkout a different branch

-Checkout different branch from the workflow repository:
 ```yaml
- uses: actions/checkout@v1
+- uses: actions/checkout@v2-beta
  with:
    ref: some-branch
 ```

-Checkout different private repository:
+## Checkout a different, private repository
+
 ```yaml
- uses: actions/checkout@v1
+- uses: actions/checkout@v2-beta
  with:
    repository: myAccount/myRepository
-    ref: refs/heads/release
-    token: ${{ secrets.GitHub_PAT }} // `GitHub_PAT` is a secret contains your PAT.
+    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).
+
+## Checkout the HEAD commit of a PR, rather than the merge commit

-Checkout private submodules:
 ```yaml
- uses: actions/checkout@v1
+- uses: actions/checkout@v2-beta
  with:
-    submodules: recursive
-    token: ${{ secrets.GitHub_PAT }} // `GitHub_PAT` is a secret contains your PAT.
+    ref: ${{ github.event.pull_request.head.sha }}
 ```
-> - `with.token` will be used as `Basic` authentication header for https requests talk to https://git.teamtekk.it from `git(.exe)`, ensure those private submodules are configured via `https` not `ssh`.
-> - `${{ github.token }}` only has permission to the workflow triggering repository. If the repository contains any submodules that comes from private repository, you will have to add your PAT as secret and use the secret in `with.token` to make `checkout` action work.

-For more details, see [Contexts and expression syntax for GitHub Actions](https://help.git.teamtekk.it/en/articles/contexts-and-expression-syntax-for-github-actions) and [Creating and using secrets (encrypted variables)](https://help.git.teamtekk.it/en/articles/virtual-environments-for-github-actions#creating-and-using-secrets-encrypted-variables)
+# License

-# Changelog
-
-## v1.1.0 (unreleased)
- Persist `with.token` or `${{ github.token }}` into checkout repository's git config as `http.https://git.teamtekk.it/.extraheader=AUTHORIZATION: basic ***` to better support scripting git

-# About:
-#
-# This is a helper script to tag and push a new release. GitHub Actions use
-# release tags to allow users to select a specific version of the action to use.
-#
-# See: https://github.com/actions/typescript-action#publishing-a-new-release
-#
-# This script will do the following:
-#
-# 1. Get the latest release tag
-# 2. Prompt the user for a new release tag
-# 3. Tag the new release
-# 4. Push the new tag to the remote
-#
-# Usage:
