Have you checked the BP documentation yet?

Have you a basic degree of HTML/PHP knowledge, you will need a basic level to be bale to copy/paste the markup structure of BP template files to match the themes structure which is what step three is about and I’m afraid is a manual process.

If you can’t manage the adjustment of the files it may be better to wait for BP 1.7 to drop as that will work with any theme.
