How to create a completly custom theme in Tuleap?

The documentation is now out-dated.

If you want to brand Tuleap to your company, you need to have the Tuleap sources and manage it as a copy of the official theme (and keep it updated each time you upgrade).

Note: there is a massive rework on all UI part underway and it will change 100% of how things are rendered. First bits will land in november and the move should completed in Spring 2017.
