If we take a look at the actions someone has to do for the setup:
- install
(SyncTrazor or Syncthing-gtk) - make sure it starts at startup (same as above)
- connect Syncthing to the internet (Firewalls etc., maybe UDP ?)
- connect devices (I imagine it to be similar to bump)
- find folders on disk and give a name
- Share
For the inexperienced user, maybe activation of the versioning would be good. (even only 30 days might help)
When considering this list, i could talk my family members through the setup, also the setting up folder, because this is always within Syncthing. I can do the same at my pc and see where they are stuck. Really difficult is only, because its different on every router, connecting syncthing to the internet.
