To get started with SlimKat, you'll need to get familiar with Git and Repo.
To initialize your local repository using the SlimKat trees, use this command:
repo init -u https://github.com/SlimSaber-JFLTE/platform_manifest.git -b jflte-mm6.0
repo sync -c -j5
5 is the number of your cpu processors + 1.
. build/envsetup.sh
lunch
Pick slimsaber_jflte-userdebug
make -j4 bacon
or
. build_rom.sh jflte c (not tested for the moment)
