The RevLog site has been built using the Concrete CMS provided by the University of Geneva.
Concrete CMS allows content to be created and edited interactively without needing to write code. It is suitable for structured editorial websites where administrators need to manage pages, navigation, and reusable content blocks.
The core official documentation can be found here: Concrete CMS official documentation
Once a user has administrative rights, the editing toolbar appears at the top of the site.
The toolbar is divided into page-specific and site-wide functions.
