 ### Overview
 
 The is a library like the [Rx.NET](https://github.com/Reactive-Extensions/Rx.NET), for the asynchronous or event-based programs on OutputRange concept.
 
-#### Basic concept interfaces
-
-```d
-//module rx.disposable
-interface Disposable
-{
-    void dispose();
-}
-
-//module rx.observer
-interface Observer(E) : OutputRange!E
-{
-    //void put(E obj); //inherits from OutputRange!E
-    void completed();
-    void failure(Exception e);
-}
-
-//module rx.observable
-interface Observable(E)
-{
-    alias ElementType = E;
-    Disposable subscribe(Observer!E observer);
-}
-
-```
