Thanks for the tip, and thanks also to peterleinchen who already sent me the file by mail

I looked over the document, and it seems to be pretty detailed.
Only small comments:

1.) in the chapter "7. Extract preinits.tar and the NITDroid files" you tell as the last thing to do is to turn off the device, to flash to open mode. I think most logical thing to do is to go to open mode before this, so put the chapter "Flash the Device with Open-Mode Kernel" before chapter 7.

2.) the last steps in the last chapter, where you copy the Noemo kernel from /boot/ of mmcblk0p4 to the /boot/ of mmcblk0p2 (to Harmattan root) is not necessary, as ubiboot can find the Nemo kernel from the Nemo partition (and with default setup it looks for it from there already...)
