 ## Define a custom rule
 
-Plugins should export a rule factory that provides type-safety that ensures compatibility with the plugin's backend. The catalog plugin exports `createCatalogPermissionRule` from `@backstage/plugin-catalog-backend/alpha` for this purpose. Note: the `/alpha` path segment is temporary until this API is marked as stable. For this example, we'll define the rule in `packages/backend/src/customPermissionRules/isInSystem`, but you can put it anywhere that's accessible by your `backend` package.
