.. _cmd-help:
help - display fish documentation
=================================
Synopsis
--------
.. synopsis::
help [SECTION]
Description
-----------
``help`` displays the fish help documentation.
If a *SECTION* is specified, the help for that command is shown.
The **-h** or **--help** option displays help about using this command.
If the :envvar:`BROWSER` environment variable is set, it will be used to display the documentation.
Otherwise, fish will search for a suitable browser.
To use a different browser than as described above, one can set the :envvar:`fish_help_browser` variable.
This variable may be set as a list, where the first element is the browser command and the rest are browser options.
Example
-------
``help fg`` shows the documentation for the :doc:`fg <fg>` builtin.
Notes
-----
Most builtin commands, including this one, display their help in the terminal when given the **--help** option.
