This isn't user-friendly for "normal" people.
Honestly, I know how to use a computer and I understand, to me unknown, software pretty easily but this I don't get! Where am I supposed to put that strange-looking line?

Either do a better instruction so non-programmer can understand it or make it more user-friendly.

The way it is now ain't help at all.

This review is for a previous version of the add-on (1.1.1). 

It would be nice if you could suggest the exact change in the instruction.

I don't know how it can be improved since it is already pointing to the configuration file and has links referring to Rspamd documentation sections where everything explained in detail.

The configuration file path is specified relative to the "/etc" directory in order to keep things as distribution-agnostic as possible.
