I recommend reading those documents to get the general idea
as how it all works; the documents are tutorials and might not
include all details.
The standard itself does include all details but may be difficult
to understand. I recommend reading some source code of a real
H.264 encoder/decoder, possibly with the help of a debugger.
JM is the "official" codec, another good source code is in the
x264 encoder.
