           token: ${{ secrets.GITHUB_TOKEN }}
 ```
 
+### Push pull request branches to a fork
+
+To enforce security, you can use a dedicated user using [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, then login with this user.
+2. fork the repository.
+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 go back to your main user.
+5. Add a secret to the repository containing the above PAT.
+6. As shown in the example below, 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
+          git fetch --unshallow -p origin
+
+      # Make changes to pull request here
+
+      - uses: peter-evans/create-pull-request@v2
+        with:
+          token: ${{ secrets.PAT }}
+          request-on-parent: true
+```
+
 ### Running in a container
 
 This action can be run inside a container by installing the action's dependencies either in the Docker image itself, or during the workflow.
