Hybrid composer - where can I find material on it?

Question

Frameworks

Hello.
I recently came across a wordpress theme built on wordpress framework-y using Hybrid composer. I decided to try and figure it out. But I did not find normal documentation on their website, I began to search in Google, the same thing. Tell me, please, with what help to understand it? And is it worth looking into?
Thanks in advance.
I ask everyone who just wants to mock or show their "mind" to go their own way, but by.
