# Modules Reference¶

Because every feature of Diofant must have a test case, when you are not sure how to use something, just look into the tests/ directories, find that feature and read the tests for it, that will tell you everything you need to know.

Most of the things are already documented though in this document, that is automatically generated using Diofant’s docstrings.
