# Checkout V2
# Checkout V4
This action checks-out your repository under `$GITHUB_WORKSPACE`, so your workflow can access it.
Only a single commit is fetched by default, for the ref/SHA that triggered the workflow. Set `fetch-depth: 0` to fetch all history for all branches and tags. Refer [here](https://help.github.com/en/articles/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.

Refer [here](https://docs.github.com/actions/using-workflows/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.
The auth token is persisted in the local git config. This enables your scripts to run authenticated git commands. The token is removed during post-job cleanup. Set `persist-credentials: false` to opt-out.
When Git 2.18 or higher is not in your PATH, falls back to the REST API to download the files.
### Note
Thank you for your interest in this GitHub action, however, right now we are not taking contributions.
We continue to focus our resources on strategic areas that help our customers be successful while making developers' lives easier. While GitHub Actions remains a key part of this vision, we are allocating resources towards other areas of Actions and are not taking contributions to this repository at this time. The GitHub public roadmap is the best place to follow along for any updates on features we’re working on and what stage they’re in.
We are taking the following steps to better direct requests related to GitHub Actions, including:
1. We will be directing questions and support requests to our [Community Discussions area](https://github.com/orgs/community/discussions/categories/actions)
2. High Priority bugs can be reported through Community Discussions or you can report these to our support team https://support.github.com/contact/bug-report.
3. Security Issues should be handled as per our [security.md](security.md)
We will still provide security updates for this project and fix major breaking changes during this time.
You are welcome to still raise bugs in this repo.
# What's new
- Improved performance
- Fetches only a single commit by default
- Script authenticated git commands
- Auth token persisted in the local git config
- Supports SSH
- 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
Refer [here](https://github.com/actions/checkout/blob/v1/README.md) for previous versions.

- uses: actions/checkout@v4

# Recommended permissions
When using the `checkout` action in your GitHub Actions workflow, it is recommended to set the following `GITHUB_TOKEN` permissions to ensure proper functionality, unless alternative auth is provided via the `token` or `ssh-key` inputs:
```yaml
permissions:
contents: read
```
