This is a demo site for Solar, generated as part of Sphinx Themes Gallery.
This sample documentation was generated on Oct 31, 2022, and is rebuilt weekly.
Install this theme:
$ pip install solar-theme
Set the following in your existing Sphinx documentation’s
import solar_theme html_theme = 'solar_theme' html_theme_path = [solar_theme.theme_path]
Build your Sphinx documentation with the new theme! 
This theme does not have any hosted-on-the-web documentation.
The Kitchen Sink section contains pages that contains basically everything that you can with Sphinx “out-of-the-box”.
Browsing through that section should give you a good idea of how stuff looks in this theme.
