Basic Rifle Training

I live in the north bay. I own rifle for home defense, it has not come out of the box since I bought it several years ago. I’m a tiny, older woman and I used to have a shotgun but the kickback was too much for me. My son (who has moved away) suggested a short-stock rifle instead, since my arms are short. I’m looking for basic training, as in how to load, point and shoot. Nothing extensive, just enough so that if necessary I could use it. Any leads on where to go?
