How To Save Instruments

I should be able to work this out but i cant seem to. How can i save renoise instruments? Would like to make a folder of kits, synthish patches etc.
Tried to find some posts about this rather than waste anyones time but couldnt in 40 mins searching.

Ah thanks banti. I knew itd be straightforward but couldnt seem to work it out.
Dont think it needs an overhaul but maybe signposting more clearly in the tutorials/documentation would be a good move because although it works fine this little aspect seems quite unlike any other bit of software ive used.
Sorry if it is in the tutorials or the html manual thing … couldnt spot it.
