miniatureCMS is a very simple CMS, that does not have many features.
I created miniatureCMS, as I needed a simple system for some of my websites. Many of the existing CMS, either have a ton of features or are buggy. At least between the ones I examined. All I needed was a system, where I could edit a few pages.
There is no media library of any sorts, so you have to upload images, that should be embedded in the pages manually. Also the editor is not WYSIWYG, so you will have to know some basic HTML to be able to edit pages.
