Does your area have any non-technical fire roads? Once she gets comfortable with shifting in a low traffic area that would be a good progression if you have easy access to them.

There are a couple of great mountain bike clinics around - there is a fantastic one on southern Indiana every June that both of you would probably love. It is the Midwest Women's Mountain Bike Clinic and it is great for all women interested in mountain biking at any level.
Did you notice OP is in Croatia? I don't think a clinic in Indiana is going to be of much help.

that being said - cover the basics in shifting, first and foremost.
After that, I suggest basic body position skills work ( neutral to attack, pedals level and butt out of the saddle) then work on braking and manuevering. Videos on YouTube can be useful. Take it slow unless she's agressive and getting it right away.
