I'm a bit confused about your question. Either you don't know how to write technical documentation. Then the scope of your question is too wide to be answered in a single answer here and you should probably at least get one or a few books or take a course on technical documentation to learn the basics. Or you don't know what the conventions and expectations are for this specific job, and then you need to ask those in your company who are in charge of that project what they want or those who will have to use the documentation what they need or both.
