I only started this thread to provide a link to the roms, as they are not available on xda until now, and a lot of users may not be aware they are still around.
Personally I have found this rom to be very stable, with some nice features.

Warning(particularly for MM builds): If you try to flash gapps, you will probably find it won't fit on the stock /system partition. In this case you will need to repatition - Repartitioning guide.
Make sure you choose a pit file that increases /system and not just /data(eg, I91001GB_4GB.pit)
Alternatively use Lanchon's re-pitting tool if you want to avoid losing your data
If you want to donate to Mokee and make their life a bit easier(donations will go towards bandwidth etc),
you can donate HERE
1. Wipe data/factory reset(from KK compatible recovery)
2. Format /system
3. Flash rom
4. Flash gapps(optional)
5. Flash isorec recovery(for MM, see below), you only need to do this once

Note: Now that Marshmallow(6.x.x) has been released, a warning for anyone flashing these latest nightlies. The kernel(isorec CM kernel) comes bundled with CM recovery, which is more or less useless. If you want a working recovery, you will need to flash the rom, followed by gapps(if you want play store), followed by an isorec recovery from HERE
Be sure to flash either CWM or TWRP for i9100. It is obvious from the name of the file.
And read about Isorec if you are not sure.
