 # Leaving the monad
 
-A [monad] (https://en.wikipedia.org/wiki/Monad_%28functional_programming%29) is an abstract concept from functional programming that is unfamiliar to most programmers. It is beyond the scope of this guide teaching monads. In www.introtorx.com we find a short definition:
+A [monad] (https://en.wikipedia.org/wiki/Monad_%28functional_programming%29) is an abstract concept from functional programming that is unfamiliar to most programmers. Teaching monads is beyond the scope of this guide. In www.introtorx.com we find a short definition:
 > Monads are a kind of abstract data type constructor that encapsulate program logic instead of data in the domain model.
 
 Monads are of interest to us, because the observable is a monad. Rx code declares what needs to be done but the actual processing happens not when Rx statements are executed, but rather when values are emitted. Readers may find it interesting to read more about monads in general. For this guide, when refering to monads the reader only needs to think about the observable.
