 The implementation of these actions are only defined once in the `actions` block of the Post resource. This lays the foundation for deriving more functionality from these actions. We could also create other resources and domains.
 
 In further sections I'll discuss
-- User and Login with `AshAuthentication`
 - Integrating Ash models with LiveView forms
-- REST API with `AshJsonApi`
-- GraphQL API with `AshGraphql`
+- User and Login with [`AshAuthentication`](https://hexdocs.pm/ash_authentication_phoenix/get-started.html)
