-To start your Phoenix server:
+An agnostic social network following the KISS and UNIX philosophy, the main principles of which are minimalism and rationalism. It implements the ActivityPub protocol and promises maximum compatibility with all existing implementations.
 
-  * Run `mix setup` to install and setup dependencies
-  * Start Phoenix endpoint with `mix phx.server` or inside IEx with `iex -S mix phx.server`
+## TODO
 
-Now you can visit [`localhost:4000`](http://localhost:4000) from your browser.
+### API
 
-Ready to run in production? Please [check our deployment guides](https://hexdocs.pm/phoenix/deployment.html).

-  Handles mounting and authenticating the current_user in LiveViews.
-
-  ## `on_mount` arguments
-
-    * `:mount_current_user` - Assigns current_user
-      to socket assigns based on user_token, or nil if
-      there's no user_token or no matching user.
-
-    * `:ensure_authenticated` - Authenticates the user from the session,

-      on user_token.
-      Redirects to login page if there's no logged user.
-
-    * `:redirect_if_user_is_authenticated` - Authenticates the user from the session.
-      Redirects to signed_in_path if there's a logged user.

-
-  Use the `on_mount` lifecycle macro in LiveViews to mount or authenticate

-        on_mount {NullaWeb.UserAuth, :mount_current_user}

-  Or use the `live_session` of your router to invoke the on_mount callback:
