Welcome to the Ansible Developer Guide!

**Who should use this guide?**

If you want to extend Ansible by using a custom module or plugin locally, creating a module or plugin, adding functionality to an existing module, or expanding test coverage, this guide is for you. We've included detailed information for developers on how to test and document modules, as well as the prerequisites for getting your module or plugin accepted into the main Ansible repository.

Find the task that best describes what you want to do:

* I'm looking for a way to address a use case:

   * I want to :ref:`add a custom plugin or module locally <developing_locally>`.
   * I want to figure out if :ref:`developing a module is the right approach <module_dev_should_you>` for my use case.

* I'm ready to start developing:

   * I want to :ref:`set up my Python development environment <environment_setup>`.
   * I want to :ref:`get started writing a module <developing_modules_general>`.
   * I want to :ref:`write a Windows module <developing_modules_general_windows>`.
   * I want to :ref:`write a series of related modules <developing_modules_in_groups>` that integrate Ansible with a new product (for example, a database, cloud provider, network platform, etc.).

* I want to refine my code:

   * I want to :ref:`debug my module code <debugging>`.
   * I want to :ref:`test my module <developing_testing>`.
   * I want to :ref:`document my module <module_documenting>`.
   * I want to :ref:`make sure my code runs on Python 2 and Python 3 <developing_python_3>`.

* I want to work on other development projects:

   * I want to :ref:`write a plugin <developing_plugins>`.
   * I want to :ref:`connect Ansible to a new source of inventory <developing_inventory>`.
   * I want to :ref:`deprecate an outdated module <deprecating_modules>`.

* I want to contribute back to the Ansible project:

  * I want to :ref:`contribute my module or plugin <developing_modules_checklist>`.
  * I want to :ref:`understand the license agreement <contributor_license_agreement>` for contributions to Ansible.
