This repository includes a Bootstrap-based Sphinx theme used for the documentation of Translate's software.
Add this repository contents as _theme into your docs folder. You can also add it as a git submodule, which is probably the best idea. You need to run the following from the root of your repository:
git submodule add git://github.com/translate/sphinx-themes.git docs/_themes/
Adjust the necessary configuration options in conf.py:
sys.path.insert(0, os.path.abspath('.'))
html_theme_path = ['_themes']
html_theme = 'sphinx-bootstrap'
