+All inputs are **optional**. If not set, sensible default values will be used.
 
 **Note**: If you want pull requests created by this action to trigger an `on: push` or `on: pull_request` workflow then you must use a [Personal Access Token](https://help.github.com/en/articles/creating-a-personal-access-token-for-the-command-line) instead of the default `GITHUB_TOKEN`. Alternatively, allow the action to [push using SSH](https://github.com/peter-evans/create-pull-request/blob/master/docs/concepts-guidelines.md#push-using-ssh-deploy-keys) by configuring a deploy key.

 1. [Create a new SSH key pair](https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key) for your repository. Do not set a passphrase.
 2. Copy the contents of the public key (.pub file) to a new repository [deploy key](https://developer.github.com/v3/guides/managing-deploy-keys/#deploy-keys) and check the box to "Allow write access."
 3. Add a secret to the repository containing the entire contents of the private key.
-4. As shown in the example steps below, use the [`webfactory/ssh-agent`](https://github.com/webfactory/ssh-agent) action to install the private key and clone your repository. Remember to checkout the `base` of your pull request if it's not the default branch, e.g. `git checkout my-branch`.
+4. As shown in the example below, configure `actions/checkout` to use the deploy key you have created.
 
 ```yml
     steps:
-      - uses: webfactory/ssh-agent@v0.2.0
+      - uses: actions/checkout@v2
         with:
-          ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}

+
+### Push pull request branches to a fork
+
+Instead of pushing pull request branches to the repository you want to update, you can push them to a fork of that repository.
+This allows you to employ the [principle of least privilege](https://en.wikipedia.org/wiki/Principle_of_least_privilege) by using a dedicated user acting as a [machine account](https://help.github.com/en/github/site-policy/github-terms-of-service#3-account-requirements).
+This user has no access to the main repository.
+It will use their own fork to push code and create the pull request.
+
+1. Create a new GitHub user and login.
+2. Fork the repository that you will be creating pull requests in.
+3. Create a [Personal Access Token (PAT)](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line).
+4. Logout and log back in to your main user account.
+5. Add a secret to your repository containing the above PAT.
+6. As shown in the following example workflow, switch the git remote to the fork's URL after checkout and set the action input `request-on-parent` to `true`.
+
+```yaml
+      - uses: actions/checkout@v2
+
+      - run: |
+          git config user.password ${{ secrets.PAT }}
+          git remote set-url origin https://github.com/bot-user/fork-project
