 defmodule MatrixAppService do
   @moduledoc """
-  MatrixAppService keeps the contexts that define your domain
-  and business logic.
+  Library that adds Matrix Application Service functionalities to Phoenix
+  applications.
 
-  Contexts are also responsible for managing your data, regardless
-  if it comes from the database, an external API or others.
+  ## Installation
+
+  Add this library to your dependencies in `mix.exs`
+
+  ```
+  defp deps do
+    [...]
+    {:matrix_app_service, "~> 0.1.0"}
+  end
+  ```
+
+  ## Usage
+
+  ### Inject routes
+
+  In your Phoenix Router:
+
+  ```
+  MatrixAppServiceWeb.Router.routes()
+  ```
+
+  ### Write adapters
+
+  Create one or multiple modules that implements the following modules:
+  `MatrixAppService.Adapter.Room`, `MatrixAppService.Adapter.User`,
+  `MatrixAppService.Adapter.Transaction`.
+
+  For instance:
+
+  ```
+  @impl MatrixAppService.Adapter.Room
+  def query_alias(room_alias) do
+    # Do something with the room alias
+    # If the room exists, return :ok
+  end
+
+  @impl MatrixAppService.Adapter.User
+  def query_user(user_id) do
+    # Do something with the user ID
+    # If the user exists, return :ok
+  end
+
+  @impl MatrixAppService.Adapter.Transaction
+  def new_event(%MatrixAppService.Event{type: type, content: content})
+    # Do something with the event
+  end
+  ```
+
+  ### Write configuration
+
+  ```
+  config :matrix_app_service,
+    transaction_adapter: App.Matrix.Transaction,
+    room_adapter: App.Matrix.Room,
+    user_adapter: App.Matrix.User,
+    path: "/matrix"
+    base_url: "http://synapse:8008",
+    access_token: "access token",
+    homeserver_token: "homeserver token"
+  ```
+
+  ### Use the Client-Server API
+
+  You can use the functions in `MatrixAppService.Client`
