+    "Syntax" to allow functions and methods to be chained, similar to
+    clojures arrow operator (``->``).
+
+    Each operation applies some kind of procedure, and forwards the
+    pipeline with the result (by returning a new Pipeline object with
+    the contained object being replaced:
+
+    ``.do`` applies a function, passing the pipelined object as the
+    first value. If another position is wanted, use a lambda.
+
+    ``.on`` Applies a method on the object. The method name needs to
+    be passed as a string due to how python works.
