It might help if you could explain what you don't understand. There's a lot of vocabulary in Mixing so it's understandable to get confused. If you do get confused just look the up! The internet is full of information after all :>
Mixing is not easy nor can you learn it that quickly and mind you, there is no universal process to take when mixing. Just take your time and read the advice that people give carefully, I cannot stress that enough.
Hopefully what I said was helpful. Good luck with mixing ;>
