``pw module check``
^^^^^^^^^^^^^^^^^^^
The ``pw module check`` command exists to ensure that your module conforms to

.. _module-pw_module-module-create:

``pw module create``
^^^^^^^^^^^^^^^^^^^^
The ``pw module create`` command is used to generate all of the required
boilerplate for a new Pigweed module.

.. note::

   ``pw module create`` is still under construction and mostly experimental.
   It is only usable in upstream Pigweed, and has limited feature support, with
   a command-line API subject to change.

   Once the command is more stable, it will be properly documented. For now,
   running ``pw module create --help`` will display the current set of options.
