One of the developers of the new site here. Simon Krajewski did an amazing job writing the manual - it's a great resource and has all the gory technical detail - I'd encourage you to take a look. A number of other people have contributed to content and design (though we'd still like to give the design some more love).
The website itself is developed in Haxe, and all of the content is hosted on Github so we can encourage contribution but still keep an eye on the quality, unlike the wiki we had previously. There's a "Contribute" link at the bottom of each page that links you to the relevant file on Github.
If you have any questions let me know, I'm happy to answer. I hope you find it a valuable resource.
