I'd suggest:

https://kernel.org/doc/html/latest/process/2.Process.html#getting-started-with-kernel-development

and

https://kernel.org/doc/html/latest/process/development-process.html

which will give you a broader picture.

You could test linux-next, build random configs:

"make randconfig"

and see if you trigger a compiler warning, try to analyze it, understand
it and fix it.

It is a steep climb but it is a lot of fun. :-)

HTH.
