Changelog

.. code:: python

 html_theme = "sphinx_rtd_theme"

Via git or download
-------------------

Symlink or subtree the ``sphinx_rtd_theme/sphinx_rtd_theme`` repository into your documentation at
``docs/_themes/sphinx_rtd_theme`` then add the following two settings to your Sphinx
``conf.py`` file:

.. code:: python

 html_theme = "sphinx_rtd_theme"
 html_theme_path = ["_themes", ]

Configuration
=============

You can configure different parts of the theme.

Project-wide configuration
--------------------------

The theme's project-wide options are defined in the ``sphinx_rtd_theme/theme.conf``
file of this repository, and can be defined in your project's ``conf.py`` via
``html_theme_options``. For example:

.. code:: python

 html_theme_options = {
     'typekit_id': hiw1hhg,
     'canonical_url':
     'analytics_id':
     'collapse_navigation': False
     'sticky_navigation': False
     'navigation_depth': 4
     'includehidden': True
     'logo_only':
     'display_version': True
     'prev_next_buttons_location': bottom
 }

The following options are available:

* ``canonical_url`` This will specify a `canonical url <https://en.wikipedia.org/wiki/Canonical_link_element>`__
to let search engines know they should give higher ranking to latest version of the docs.
The url points to the root of the documentation and requires a trailing slash.
* ``includehidden`` Specifies if the global toctree includes toctrees marked with the `:hidden:` option
* ``prev_next_buttons_location`` can take the value ``bottom``, ``top``, ``both`` , or ``None``
and will display the "Next" and "Previous" buttons accordingly

Page-level configuration
------------------------

Pages support metadata that changes how the theme renders.
You can currently add the following:

* ``:github_url:`` This will force the "Edit on GitHub" to the configured URL
* ``:bitbucket_url:`` This will force the "Edit on Bitbucket" to the configured URL
* ``:gitlab_url:`` This will force the "Edit on GitLab" to the configured URL
