      Find out how to get help with Spack, including using the spack help command.

Getting Help
============

.. _cmd-spack-help:

``spack help``
--------------

If you don't find what you need here, the ``help`` subcommand will print out a list of *all* of Spack's options and subcommands:

.. command-output:: spack help

Adding an argument, e.g., ``spack help <subcommand>``, will print out usage information for a particular subcommand:

.. command-output:: spack help install

Alternatively, you can use ``spack --help`` in place of ``spack help``, or ``spack <subcommand> --help`` to get help on a particular subcommand.
