Ensure configuration documentation is accurate, consistent, and clearly indicates optional versus required values. Use consistent terminology throughout documentation, provide accurate technical details, and make examples actionable for developers.

Key practices:

Example of good documentation structure:

*position* "None" | { x = <integer>, y = <integer> }

    Window startup position

    Specified in number of pixels.

    If the position is _"None"_, the window manager will handle placement.
    
    Default: _"None"_

This approach helps developers understand exactly what configuration options are available, what values are valid, and how to properly use them in their own configurations.
