If you already have these:
- A linux Environment (Recommended : Ubuntu 20.04 LTS)
- A decent Internet Connection (You should be able to download at least 500 Kb in a Second) Because ROM sources could be 16 GB approx. even when shallow cloned.
- RAM: 8 GB Minimum (+ ZRAM + SWAP optional)
- CPU: 4 core 8 thread is the bare minimum or else it takes an eternity to build
- Storage: SSD is better and it will build if you have HDD too.. 250GB is a decent amount of space
- Some "NOT_A_RETARD" Linux knowledge and Basic ideas about Git.
- You need to have the TREES.. ( Device Tree , Kernel Tree {Or use a prebuilt one - not recommended} , Vendor Tree {And A Common Tree if available})
- A GitHub Account or a GitLab account! (Preferably with the trees forked/imported)
*Yaay! You're ready to build
