+========================
+OnAny... thing happening
+========================
+
+OnAny is a simple yet powerful event manager library, where you can declare listeners and dispatch as much events as needed to them.
+
+How To
+======
+To listen and dispatch events is very simple:
+
+.. code :: python
+    
+    from onany import dispatch, listener
+
+    @listener("event.name")
+    def on_event_name(*args, **kwargs):
+        print("I've been called with {} and {}".format(
+            args,
+            kwargs
+        ))
+
+    >>> dispatch(
+        "event.name",
+        "first_param",
+        "second_param",
+        "third_param",
+        first="param",
+        second="param",
+        third="param")
