Are questions about writing/improving documentation appropriate and on-topic for Code Review? And if so, should there be a documentation tag?
Let's be clear--I'm not talking about questions seeking help interpreting official documentation from Apple, Java, Microsoft, etc. These questions, if anything, would be more appropriate on Stack Overflow.
I'm also not talking about self-documentation via class/method/variable names and comments (although questions looking for help with these things could also use a "documentation" tag).
Instead, I'm talking about... suppose I've written a small open-source project and posted it on GitHub. I feel confident about my code and I'm not interested in the code being reviewed. Instead, I'd like help writing and improving the official documentation that I'm providing to go with the project so that future users can most easily understand what all the methods and properties and variables etc are all there for and what they all mean and how the project should be used.
