Can someone explain to me the brief process used to create the meta-pine64 minimal image here?

I’m asking this because I’m very new to the Yocto project. I’m going through the documentation but it’s a bit overwhelming to me, looking at what Fishwaldo has achieved (link embedded in the title). I would like to learn how he did it and how I could create my own image based on a supported kernel with necessary drivers and boot the Star64 board.

From what I understand, he:

1. Forked the kernel tree and created his own branch.
2. Put in the necessary drivers (including OEM drivers) - I’m not really sure how he did it since I’m new to Linux (any tips would be appreciated!).
3. I can’t quite make out the layers he used to build the minimal image (I will study the guide more to figure this out).
4. Finally, he compiled it, alongside compiling U-boot, partitioned the SD-card and booted the device.

Am I right? I’m missing a lot of steps in the middle, would really appreciate any help in understanding this. Thanks!
