 momepy API reference
 ======================
 
-elements
---------
+The current version of momepy includes two implementations of most of the functionality
+due to the ongoing migration period moving from the legacy class-based API to a new
+function-based API. This page outlines the stable API. For the legacy functionality, see
+:doc:`Legacy API  <legacy_api>`.
+
+Managing morphological elements
+-------------------------------
+.. _elements:
+
+Momepy allows creation of a small subset of bespoke morphological geometric features.
