How and when inform support

How has the less literate user to do if it finds a system log errors and or other warnings. Alternatively, the errors on the main page in Foris.

Where can I find a suitable procedure? What documents to send to aid? I’ll find somewhere how to what to send to support? Diagnostics, System log file form LuCI, what et cetera.

On what issues should or should not do.

Thank you
