Themes allow you to change the look and feel of your Drupal site. You can use themes contributed by others or create your own to share with the community. Contributed themes are not part of any official release and may not have optimized code/functionality for your purposes.
You can also create a sub-theme of an existing theme. A sub-theme inherits a parent theme's resources. Read more about Sub-theme structure and inheritance.
You can also view a full index of themes listing only their titles.

I am still developing this Drupal 8 contributed theme. It is not ready for primetime.
My goals with the Atomic theme are to create a base theme that provides an approachable starting point for sub themes. Atomic uses Sass and a number of Compass gems: by making a few initial global design choices, you can get up and running with some sensible defaults. Partials are broken down to let you easily provide essential base styles for elements or regions, while focusing on component styles, and keeping those styles separate from layout styles.
Bootstrap ignitor is a sub theme of the
[Bootstrap Drupal theme](https://drupal.org/project/bootstrap). It facilitates
speedy development by taking care of the mundane tasks usually associated with
setting up the Bootstrap theme.
You should create a subtheme of this theme to use as your actual theme or use
the "Bootstrap Starter" theme as a subtheme of this theme (recommended).
