Hi developers,
for streamlining (my) support (to users), I created a kind of
first aid checklist [1]
which I ask users coming with questions to read and answer first. If possible.
- adapted to my needs - comprises most of the questions and "have you already done this and that" I needed to ask them over and over again - currently not a template (I don't think that this is necessary or useful at the moment)
You may also find it useful for integrating, adapting to your needs, on your extension or whatever page/s.
