The best thing to do is ask questions on these topics, and then submit 
suggestions for the Yocto Project manual.

Much of this code predates the documentation, and is considered "advanced"

features exists.

Add a docs bug in the yocto project bugzilla, we want to start enhancing the 
manual with more advanced topics.
