Cairo Desktop Environment

Why is this website so completely devoid of information? Why is there only one page. Why is the only link to GitHub?

How old is this? Why are all the examples in the screenshots on this extremely limited page so out of date (Non-Chrome Edge, Skype for Business, Office 2016, etc). Is this a dead project? The Releases page makes it appear to not be, but the website is so ancient that's the initial impression.

The GitHub page contains almost no additional information and the same ancient screenshots.
