Looking at documenation
There is three big clickable images on top, but they lead nowhere.
Perhaps they should be removed, this is misleading and looking unfinished page.
On bottom page you have a link to CryEngine
You should perhaps remove it, i never seen a 3D engine doc referencing other 3D engines links
Another issue is blocks of text for tutorials, for example :
I don't think somone will read all that block of unformatted text. Some pictures would explain better or a video tutorial.
Perhaps some pages should be removed or changed ?
