Atlas features an alternate topic list layout intended to highlight topic excerpts, and also includes space for an (optional) sidebar. Categories feature user-dismissable headers populated by the “About” topic.
The sidebars are added using the Custom Sidebar component , which can be setup to feature a post as the sidebar content for specified categories. Configuration details are in the repo’s readme.
The theme works best with the box category style (admin > settings)
Excerpts can be enabled using a hidden site setting called always_include_topic_excerpts. To enable this setting you need console access to your server.
To enable excerpts via the command line
./launcher enter app
rails c
and then in the rails console
SiteSetting.always_include_topic_excerpts = true

There are some hard-coded colors in this theme, I need to update those to be editable by color schemes
Settings to turn certain features (like category headers) on and off
Thank you for the good work, is there a way to change header color from black to probably a light one i.e. white?
I am novice here, so advance many thanks for answering a basic question.
