cdist is a usable configuration management system.
It adheres to the KISS principle and is being used in small up to enterprise grade environments.
For more information have a look at homepage
or at docs/src for manual in reStructuredText format.
Merge/Pull requests can be made in both upstream GitLab (managed by ungleich) and GitHub project.
Issues can be made and other project management activites happen only in GitLab (needs ungleich account).
For community-maintained types there is cdist-contrib project.
