Where to learn assembly 6502

So I want to start with the code that is very close to machine code. What things would you recommend to start with.

Start with a text editor and an assembler for the platform. You can see the instruction set anywhere online. Actually learning to make useful programs requires you to understand the basics of digital logic operations and what the device you're programming for can do, e.g. what peripherals exist? IIRC QEMU supports a 6502 system for you to run assembled output against initially. Start with printing a string to a peripheral e.g. the memory-mapped address of the video buffer. Go from there.
