Add more examples how to use lib

[Vanish404]

Unfortunately, I didn't fully get the idea on how to use the library. How I can build something similar that I can see on the screenshots? Initially, when I went through the documentation I would be say that is possible, but when I try to build the POC I understand that is not possible to create something similar that I can see on the screenshoots, for example I didn't find filename and icons header for each file. I understand that I can create it by using Decorators, but it would be good to have it inside "black box".

Also site isn't working for diff text visualization. I tried to do it locally and on the github pages.
