+
+
+        If something isn't working right, you have questions or need help, [**create a discussion instead**](https://github.com/derekantrican/GAS-ICS-Sync/discussions).
+
+
+        Only proceed here if you are 100% sure the issue you are seeing is actually a bug. If in doubt, check
+        the discussions first, we can always file a bug from a support request later.
