+* Each module should be self-contained in one file, so it can be auto-transferred by Ansible.
 * Module name MUST use underscores instead of hyphens or spaces as a word separator. Using hyphens and spaces will prevent Ansible from importing your module.
 * Always use the ``hacking/test-module.py`` script when developing modules - it will warn you about common pitfalls.
 * If you have a local module that returns facts specific to your installations, a good name for this module is ``site_facts``.

 Introduction to ad-hoc commands
 *******************************
 
-An Ansible ad-hoc command uses the `/usr/bin/ansible` command-line tool to automate a single task on one or more managed nodes. Ad-hoc commands are quick and easy, but they are not re-usable. So why learn about ad-hoc commands first? Ad-hoc commands demonstrate the simplicity and power of Ansible. The concepts you learn here will port over directly to the playbook language. Before reading and executing these examples, please read :ref:`intro_inventory`.
