-## Submitting a pull request
-
-1. Fork and clone the repository
-1. Configure and install the dependencies: `npm install`
-1. Create a new branch: `git checkout -b my-branch-name`
-1. Make your change, add tests, and make sure the tests still pass: `npm run test`
-1. Make sure your code is correctly formatted: `npm run format`
-1. Update `dist/index.js` using `npm run build`. This creates a single javascript file that is used as an entrypoint for the action
-1. Push to your fork and submit a pull request
-1. Pat yourself on the back and wait for your pull request to be reviewed and merged
-
-Here are a few things you can do that will increase the likelihood of your pull request being accepted:
-
-- Write tests.
-- Keep your change as focused as possible. If there are multiple changes you would like to make that are not dependent upon each other, consider submitting them as separate pull requests.

 # What's new
 
-Please refer to the [release page](https://github.com/actions/checkout/releases/latest) for the latest release notes.
+- Improved performance
+  - Fetches only a single commit by default
+- Script authenticated git commands
+  - Auth token persisted in the local git config
+- Creates a local branch
+  - No longer detached HEAD when checking out a branch
+- Improved layout
+  - The input `path` is always relative to $GITHUB_WORKSPACE
+  - Aligns better with container actions, where $GITHUB_WORKSPACE gets mapped in
+- Fallback to REST API download
+  - When Git 2.18 or higher is not in the PATH, the REST API will be used to download the files
+  - When using a job container, the container's PATH is used
+- Removed input `submodules`
+
+Refer [here](https://github.com/actions/checkout/blob/v1/README.md) for previous versions.

-
-## Purpose
-
-`test-ubuntu-git` is a container image hosted on the GitHub Container Registry, `ghcr.io`.  
-
-It is intended primarily for testing the [`actions/checkout` repository](https://github.com/actions/checkout) as part of `actions/checkout`'s CI/CD workflows.
-
-The composition of `test-ubuntu-git` is intentionally minimal.  It is comprised of [git](https://git-scm.com/) installed on top of a [base-level ubuntu image](https://hub.docker.com/_/ubuntu/tags).
-
-# License
-
-`test-ubuntu-git` is released under the [MIT License](/LICENSE).
