+  * ### Why do I get the error '*Resource not accessible by integration*'?
+
+    This will happen if you use ```secrets.GITHUB_TOKEN```.
+
+    You need to create a [personal access token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) instead, and store its value in a secret, for example ```MY_TOKEN```.
+
+    Then refer to it like this:
+
+    ```yaml
+    token: ${{ secrets.MY_TOKEN }}
+    ```
