-## Endpoint
+## Endpoints
+
+Currently, the only endpoint for the application is `/update-files`, which is used to update the local files on every push as well as run post-update scripts.
+
+Since only the `/update-files` endpoint is implemented, the configuration file may not contain the `run-scripts` field.
