The internet is full of information on how to grow cannabis... start there. You'll have to make your own decisions on how to germinate, what kind of nutrients you use, lights/tent/humidity control/etc if you grow indoors... there's a lot to it! If I were you, I'd put the seeds in a dark plastic somethingorother and stick them in your refrigerator while you do some research... they'll last quite a long time so there's no hurry but you want to make sure your storage is absolutely dark and without humidity...
Good luck.
