This document describes Streamlined CMS, a Drupal distribution from Smile focused on usability. It includes reusable design system components, integrates with existing design systems like Bootstrap, and allows non-technical users to build sites through a no-code interface. Streamlined CMS is well-suited for agencies implementing Drupal at scale through a "webfactory" approach. It has been successfully used to build sites for clients like LVMH and the French government.
