The answer would depend on what programming experience you have?
Do you have any assembly language experience ? with other targets?
ie have you used an assembler ( and maybe linker ) before.
Are you familiar with hex? bytes, bits etc , You will learn this and much more …

Id look for a book that targets Assembly programming on a Apple 2, ie not a book on general 6502 programming.

   Such a book Id expect to discuss things like Apple 2 memory map , Apple 2 hardware and how they are used in assembler language. 

Hopefully the book would also provide guidance using a particular assembler ( hopefully still available)

I googled phrase
Apple 2 assembly language programming for beginners?

and lots of very good looking links popped up.

You aim is a challenging task. Much to learn. Good luck. However entirely do able these days.

My background is electronics engineer, embedded programing on in assembler (some Motorola processors and others) and C for a few years before moving on to other things ….
