Kirby is a simple file-based cms, made by Bastian Allgeier. At 6Wunderkinder we're using it as an internal knowledge-base for any type of documentation (processes, products, API...). It took us a long time to find the best setup for this and because we think most companies are struggling with this, we decided to open-source it.
Installing this is super simple!
Tip: We highly recommend to use Kirby with Dropbox - locally and on your server and to share the content folder with everyone in the team to make editing content extremely simple.
