 ## How to use it
 
 To add a Wayland compositor to your application all you have to do is create a
-CasildaCompositor widget.
+CasildaCompositor widget and pack it as any other widget.
 
-You can specify which UNIX socket the compositor will listen for clients
-connections or let it will choose one automatically.
-
-```
-compositor = casilda_compositor_new ("/tmp/casilda-example.sock");
-gtk_window_set_child (GTK_WINDOW (window), GTK_WIDGET (compositor));
-```
-
-Once the compositor is running you can connect to it by specifying the socket
-in WAYLAND_DISPLAY environment variable.
-
-```
-export GDK_BACKEND=wayland
-export WAYLAND_DISPLAY=/tmp/casilda-example.sock
-gtk4-demo
-```
-
-If you do not want any client being able to connect to the compositor you can
-pass NULL as socket and spawn the client with casilda_compositor_spawn_async()
-or get an already connected socket with casilda_compositor_get_client_socket_fd()
-and pass it to the client on WAYLAND_SOCKET env variable.
-
-```
+```c
 compositor = casilda_compositor_new (NULL);
 gtk_window_set_child (GTK_WINDOW (window), GTK_WIDGET (compositor));
 gtk_window_present (GTK_WINDOW (window));
+```
 
+The easiest way to show another process window in the compositor is to spawn the
+process using the helper function provided by Casilda
+
+```c
 gchar *argv[] = { "/usr/bin/gtk4-demo", NULL };
 casilda_compositor_spawn_async (compositor, NULL, argv, NULL, G_SPAWN_DEFAULT, NULL, NULL, NULL, NULL);
 ```
 
 ## API
 
-The api is pretty simple CasildaCompositor.
-
-Properties:
-
-- socket: The unix socket file to connect to this compositor (string)
-- scrollable: True to make widget scrollable.
-
-Methods:
-
-- `casilda_compositor_get_client_socket_fd ()`
-  Create a client socket file descriptor connected to this compositor ready to use by passing it to a client with
-  WAYLAND_SOCKET environment variable.
-
-- `casilda_compositor_spawn_async ()`
-  Executes a child program asynchronously with the right environment to automatically connect to this compositor.
+Casilda uses gi-docgen to generate it API reference documentation
