This documentation is being updated and is woefully incomplete 8-/ It's hard to do everything by yourself
I'm currently working on DomUI 2.0. This will be a big change where a lot of problematic things will be rewritten. As a consequence the master branch's code is unstable and a work in progress. This also has its effect on the demo application as that is also updated, changed, and uses the unstable 2.0 master.
We can always hope, can't we?
