 About ReactiveX
 ---------------
 
-ReactiveX for Python (RxPY) is a set of libraries for composing asynchronous and
-event-based programs using observable sequences and pipable query operators in Python.
-Using Rx, developers represent asynchronous data streams with Observables, query
-asynchronous data streams using operators, and parameterize concurrency in data/event
-streams using Schedulers.
