I wonder if the index gives a better entry to the documentation. The problem I see is that neither the index page nor the sidebar make it easy to actually scan and navigate the documentation topics:
Not sure if there’s an obvious solution? There are patterns for better sidebar layouts from existing documentation platforms. But would these improve our case without doing more work on the actual organization of topics? They might not work well for the community wiki in general.
Maybe a right sidebar that has more of a table of content layout, rather than the current narrow left sidebar, would work better?
