 ## Pipelines and Composition
 
-Pipe operators (`|>`, `<|`, `||>`, `<||`, `|||>`, `<|||`) and composition operators (`>>` and `<<`) are used extensively when processing data in F#.  These operators are functions which allow you to establish "pipelines" of functions in a flexible manner.  The following example walks through how you could take advantage of these operators to build a simple functional pipeline.

+[!code-fsharp[Pipelines](../../samples/snippets/fsharp/tour.fs#L227-L282)]
 
-The above sample made use of many features of F#, including list processing functions, first-class functions, and [partial application](language-reference/functions/index.md#partial-application-of-arguments).  Although a deep understanding of each of those concepts can become somewhat advanced, it should be clear how easily functions can be used to process data when building pipelines.
