Links to other notes


Hello everyone.
I see markdown allows to link to websites. Does it allow to link to other notes?
I’ve tried something like [word] (OtherNoteTitle) and [word] (./OtherNoteTitle) (without space, obviously) but it doesn’t work: it leads me to my own file system.
Perhaps I should link to the file but what are the extensions of the note files?
Or it may not exist at all? Could it be implemented?
Thank you.

Edit : Oups, my bad. Took some time to find the topic :
