   We built a FOSS documentation CMS with a pretty GUI▲165

   Kalmia started as a small hobby project about two months ago, but it quickly evolved when we needed a better solution to manage our office's documentation. It has now become our go-to tool for both internal and user-facing docs. Recently, we decided to open source it, as we believe others might benefit from a lightweight, customizable documentation system like this. We're excited to see how the community can take it further, contribute, and adapt it to their own needs!
