I have done it with all my QTs, so I assume it works for them all. I'm not sure what you are wondering about the add node section, but to add a node in the console you type;
addnode 123.123.123 add
Nodes are your connections to the network and has nothing to do with mining itself
In the conf.file you type;
addnode=123.123.123
To clarify if confused; you change 123.123.123 to the actual node/address
