til / writing good documentation
Writing good documentation is hard. Remember that you are writing for humans. It might be the first time they are seeing code like the one you are describing.
Everyone has at least one example of good documentation. Write your documentation as that example, the way you would want to find it. Explain in plain words as everyone might not have the same level of knowledge as you do.
There are tools that help with generating documentation, but it does not help you write good documentation. Generate documentation when possible, but put in extra effort to make it good.
