I think one place it start is finding an example of some "quick work" contributed by developers, and think about all the different corner cases to cover.
Stuff to think about:
- When to use the name of the command vs. the name of tool (e.g. Load Test vs. loadtest)
- When to use pre-formatted text for commands, e.g. loadtest vs
loadtest
- What's the principle for organizing headings and subheadings?
The MongoDB Style Guide is a good reference as well. We base a lot of our docs work off MongoDB docs.
