The directions are the same as github's. And I deviated from the both directions in that when installing kpvbooklet, I added the bin file to the mrpackages file and triggered :log mrpi to install (they asked me to install via kual helper, but your forum seemed to indicate that my device should use the MRpi method for bin files) and then I installed koreader (one koreader root file and separate one placed in the extensions file).
To install the jailbreak I followed your instructions, which were very clear by the way - Thank you.

I completed all the steps in the right order before trying to install koreader.
