 How to Update Precompiled Dependencies
 ######################################
 
+For dependencies included in zips to be usable with Lambda Layers, files must reside within a ``python`` directory. See the
+AWS `documentation <https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html#configuration-layers-path>`_
+for more information.
