+## FAQ
+
+* My project uses git lfs storage; how should I adapt the action?
+
+  If your project uses git lfs storage, you must opt-in to git lfs during `checkout` step.
+
+  ```yaml
+        - name: Check out repository
+          uses: actions/checkout@v4
+          with:
+            lfs: true # needed when using lfs for image storage
+  ```
+
+  See the [checkout action documentation](https://github.com/actions/checkout) for details.
