-The Action will only commit files back, if changes are available. The resulting commit **will not trigger** another GitHub Actions Workflow run!
+## Example
 
-We recommend to use this Action in Workflows, which listen to the `pull_request` event. You can then use the option `branch: ${{ github.head_ref }}` to set up the branch name correctly.
-If you don't pass a branch name, the Action will try to push the commit to a branch with the same name, as with which the repo has been checked out.
+In this example, we're running `php-cs-fixer` in a PHP project to fix the codestyle automatically, then commit possible changed files back to the repository.
 
-## Example Usage
-
-This Action will only work, if the job in your Workflow changes files.
-The most common use case for this, is when you're running a Linter or Code-Style fixer on GitHub Actions.
-
-In this example I'm running `php-cs-fixer` in a PHP project.

-### Example on `pull_request` event

+## Limitations & Gotchas

+### Checkout the correct branch
+
+You must use `action/checkout@v2` or later versions to checkout the repository.
+In non-`push` events, such as `pull_request`, make sure to specify the `ref` to checkout:
 
 ```yaml
-name: php-cs-fixer
-
-on: push
-
-jobs:
-  php-cs-fixer:
-    runs-on: ubuntu-latest

 ```
 
-### Inputs
+You have to do this do avoid that the `checkout`-Action clones your repository in a detached state.
+
+### Commits of this Action do not trigger new Workflow runs
+
+The resulting commit **will not trigger** another GitHub Actions Workflow run.
+This is due to [limititations set by GitHub](https://help.github.com/en/actions/reference/events-that-trigger-workflows#triggering-new-workflows-using-a-personal-access-token).
+
+> When you use the repository's GITHUB_TOKEN to perform tasks on behalf of the GitHub Actions app, events triggered by the GITHUB_TOKEN will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs.
+
+You can change this by creating a new [Personal Access Token (PAT)](https://github.com/settings/tokens/new),
+storing the token as a secret in your repository and then passing the new token to the [`actions/checkout`](https://github.com/actions/checkout#usage) Action.
+
+```yaml
+- uses: actions/checkout@v2
+  with:
+    token: ${{ secrets.PAT_TOKEN }}
+```
+
+### Unable to commit into PRs from forks
+
+GitHub currently prohibits Actions to push commits to forks, even when they created a PR and allow edits.
+See [issue #25](https://github.com/stefanzweifel/git-auto-commit-action/issues/25) for more information.
+
+## Inputs
 
 Checkout [`action.yml`](https://github.com/stefanzweifel/git-auto-commit-action/blob/master/action.yml) for a full list of supported inputs.
 
 ## Outputs
+
 You can use these outputs to trigger other Actions in your Workflow run based on the result of `git-auto-commit-action`.
 
 - `changes_detected`: Returns either "true" or "false" if the repository was dirty and files have changed.
 
 ## Troubleshooting
 
-### Can't push commit to repository
-If your Workflow can't push the commit to the repository because of authentication issues, please update your Workflow configuration and usage of [`actions/checkout`](https://github.com/actions/checkout#usage). (Updating the `token` value with a Personal Access Token should fix your issues)
+### Action does not push commit to repository
 
-### Commit of this Action does not trigger a new Workflow run
-As mentioned in the [Usage](#Usage) section, the commit created by this Action **will not trigger** a new Workflow run automatically.
+Make sure to [checkout the correct branch](#checkout-the-correct-branch).
 
-This is due to limitations set up by GitHub:
+### Action does not push commit to repository: Authentication Issue
 
-> An action in a workflow run can't trigger a new workflow run. For example, if an action pushes code using the repository's GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.
-[Source](https://help.github.com/en/actions/reference/events-that-trigger-workflows)
+If your Workflow can't push the commit to the repository because of authentication issues,
+please update your Workflow configuration and usage of [`actions/checkout`](https://github.com/actions/checkout#usage).
 
-You can change this by creating a new [Personal Access Token (PAT)](https://github.com/settings/tokens/new), storing the token as a secret in your repository and then passing the new token to the [`actions/checkout`](https://github.com/actions/checkout#usage) Action.
