+The API Doc will be available by default at `/api/` path. If you wish to
+override this path, you may set the `routePath` option. To skip adding a
+route altogether, set the `addRoute` option to false. You will still be
+able to reference schema elements manually using [Schema Imports](/docs/guides/schema-imports).
