1. Generating signing keys (Part 1)
2. Generating signing keys (Part 2)
3. Making signed build (recovery)
4. Making signed build (fastboot)
5. Making incremental update

Requirements

# First time building A12
Open terminal and run:

sudo bash
mkdir /mnt/ccache
exit
sudo mount --bind /home/masemoel/.ccache /mnt/ccache
export USE_CCACHE=1 && export CCACHE_EXEC=/usr/bin/ccache && ccache -M 60G && export CCACHE_DIR=/mnt/ccache

(set ccache -M with the maximum of GB of your disk you wanna set available for ccache, and home/masemoel with home/ and your username on your Linux environment).
