aloe plants

Just a quick question - I've inherited an aloe plant from a former co-worker, but I don't know how much I should be watering it. She left it in the store when she quit, and I don't know how much she was watering it, and no one else seems to know, either. It gets a lot of sun (is this good for aloe?) but the tips are turning yellow. I assumed that's from too little water? Thanks!
