# Appendix: Module Utilities

Ansible provides a number of module utilities that provide helper functions that you can use when developing your own modules. The basic.py module utility provides the main entry point for accessing the Ansible library, and all Ansible modules must, at minimum, import from basic.py:

    from ansible.module_utils.basic import *

The following is a list of module_utils files and a general description. The module utility source code lives in the ./lib/module_utils directory under your main Ansible path - for more details on any specific module utility, please see the source code.
