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.
I also am unable to successfully open the the theme in theme creator.
I use the “review on theme creator” link in the main post, and it takes me to the " View Shared Theme" modal on the https://theme-creator.discourse.org/latest url, but after clicking the “View Theme” button, I am left at this url: without visiting the theme: https://theme-creator.discourse.org/c/blog/18
I haven’t looked into this yet, but looks like there are some issues with this theme now on Discourse 2.7.0 beta1. If you look at it in the theme creator it is missing the topic previews and some other icons
