I help maintain open source docs at Pantheon, a website management platform for WordPress and Drupal. The docs are built with Sculpin and continuously delivered. Code and content are maintained on GitHub. Commits pushed to the repository from internal contributors are built on CircleCI, then tested and deployed to an isolated Multidev environment for peer review. The automated test suite currently includes sitespeed.io, Behat, HTMLProofer, and A11y.
