How to install ibus typing booster?

The homepage has no docs for ubuntu installation: http://www.typingbooster.org/howtoinstall/

The package request on debian was not done: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=729851

How can I get this running on ubuntu?

I want to use it for english and german texts.
