Kirby is a flat-file CMS based on text files and assets organized in nested folders. No database needed. That makes it really easy to install and to work with in the first place.
All content is stored in files and folders within the content folder. Each folder you create represents a page that is accessible via its own URL.
If you create a folder called blog as direct child of the content folder, it will be accessible via https://yourdomain.com/blog etc.

The team behind Kirby is small. Do I have to fear, that I now start working for my clients using Kirby and at some point I am left alone with a CMS that is not supported anymore?
