-
Ask the main part of your question in the title. This should be concise but informative.
-
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
-
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
-
Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

IDK really, perhaps you can use a book.
I mainly did it in the 8085 practicals during B.Tech and they had a handy learning kit with a HEX keyboard so we could Assemble it manually on paper, write the program directly to a given RAM address and then run it from there. For ARM, we just used Keil µVision.
Now I just download an x64 instruction manual or just look up the instructions on the web, on the occasional requirement of reading disassembly.
I don't recommend starting with x86_64 reference. While it can be used just fine, it has lots of instructions and and you instead want a very small subset of them.
Also, there will be a great difference between using an OS and not doing so, as going with one, then includes a lot of potential boilerplate.
