 ### How to use it
-``lasse`` provides a [cowboy loop handler](http://ninenines.eu/docs/en/cowboy/HEAD/guide/loop_handlers/) called ``lasse_handler`` that describes a behaviour. To include it in your server routes, just add the following tuple to your [dispatch routes](http://ninenines.eu/docs/en/cowboy/HEAD/guide/routing/):

+Additionally, in your module, you have to implement the ``lasse_handler`` behaviour and its

 ```erlang
 -behaviour(lasse_handler).
 ```
+
+#### Examples
+
+You can find some example applications that implement the ``lasse_handler`` in the ``examples`` folder.
+
+Running the examples is as simple as executing ``make run``, given you have the ``make`` tool
+and ``erlang`` installed in your environment.

+<a name="callbacks"></a>
+#### Callbacks
+
+##### init(InitArgs, Req) -> {ok, NewReq, State} | {shutdown, StatusCode, Headers, Body, NewReq}
+
+Will be called upon initialization of the handler, if everything goes well it should return
+``{ok, NewReq, State}``, otherwise ``{shutdown, StatusCode, Headers, Body, NewReq}`` which will
+cause the handler to reply to the client with the information supplied and then terminate.
+
+Types:
+- InitiArgs = any()
+- Req = cowboy_req:req()
+- NewReq = cowboy_req:req()
+- State = any()
+- StatusCode = cowboy:http_status()
+- Headers = cowboy:http_headers()
+- Body = iodata()
+
+##### handle_notify(Msg, State) -> Result
+
+Receives and processes in-band messages sent through the ``lasse_handler:notify/2`` function.
+
+Types:
+- Msg = any()
+- State = any()
+- Result = [result()](#result_type)
+
+##### handle_info(Msg, State) -> Result
+
+Receives and processes out-of-band messages sent directly to the handler's process.
+
+Types:
+- Msg = any()
+- State = any()
+- Result = [result()](#result_type)
+
+##### handle_error(Msg, Reason, State) -> NewState
+
+If there's a problem while sending a chunk to the client, this function will be called after which the handler will terminate.
+
+Types:
+- Msg = any()
+- Reason = atom()
+- State = any()
+- NewState = any()
+
+##### terminate(Reason, Req, State) -> ok
+
+This function will be called before terminating the handler, its return value is ignored.
+
+Types:
+- Reason = atom()
+- Req = cowboy:http_headers()
+- State = any()
+
+#### Types
+
+<a name="result_type"></a>
+##### result() = {'send', Event :: event(), NewState :: any()}
+    | {'nosend', NewState :: any()} |
