I need a Blue Manual for Beginners

Dear Community,
I will start with Programming CSound in Blue.
For a while I have learned a little bit of CSound and try to use it with Cabage.
Now I try to reuse my little knowledge of CSound to do it in Blue.
So I need two things:
1.) A little CSound Crash Course to remember my CSound Knowledge
2.9 A good introduction Manual for learning to do it in Blue.

I hope anybody can help me and give me Links and Advertises to this Content
In hope anybody can Help me
