-### Trigger action from a `pull_request_target` instead of `pull_request` event

-The action by default verifies that the [trigger][trigger_doc] is a `pull_request` event - which is the most secure and safest way to run your builds. If necessary, you can use the `event-name` property to reconfigure this verification check to support `pull_request_target` events. Make sure that you understand the [security risks][security_blog] of this behavior first. Additionally, ensure that your `checkout` action is configured properly to check out and test the right branch:
-
-```yaml
-- name: Checkout
-  uses: actions/checkout@v3
-  with:
-    ref: ${{ github.event.pull_request.head.ref }}
-    repository: ${{ github.event.pull_request.head.repo.full_name }}
-```
