We haven’t had time to start writing any troubleshooting documents to set an example but in my mind the premise for a troubleshooting document should usually be… “This was working fine and now its not!” or “I did what I supposed to and its still not working, what am I missing?” The troubleshooting document should give you a checklist of different things that could have gone wrong that you can check yourself and and it should probably link to the official how-to for the process but the difference is the how-to documents are more oriented to setting things up for the first time.
