The reality

Your Starlight docs work fine.
Finding stuff in them? Not so much.

Developers skip the search and go straight to Slack. We can fix that (and save your sanity).

Analyze questions and gaps
Users get answers to their technical questions. Analytics show you which content gaps to fill before they become support tickets.
