Some thoughts :

It wasn't absolutely clear to me what this is. The front page (project page) doesn't have a simple, clear description of the application. Or is it a "platform"?

Documentation page has a list of features - but they are all quite technical, not end-user helpful in general. The "getting started" page says :

"rapid development of robust and highly performant websites with content management functionality."

Wordpress is mentioned a lot so I assume it is a "blogging" platform to a major degree. A demo site might help but first, a better description I think.
