+Now your app is configured to use Supabase authentication.
 
 Try it out by running `yarn dev:web` and navigating to `http://localhost:3000`.
 
+## Additional resources
+
+If you need access to `auth.users` table of Supabase, you can use the Supabase utilities from `drizzle-orm/supabase`.
+
+```tsx
+import { authUsers } from 'drizzle-orm/supabase'
+```
+
+More information here: [drizzle-orm/supabase](https://github.com/drizzle-team/drizzle-orm/tree/main/src/supabase)
+
+Drizzle also supports [Row-level security (RLS)](https://orm.drizzle.team/docs/rls), which allows you to configure policies and roles for accessing data in your database.
