6 month old and solids...

I'm a first time mom, with really no friends. So I don't know who to ask or go to for advice. My baby girl will be 6 months in a week. She still only on formula. I've tried apple sauce type food, it's the Gerber can and she ate it just fine. But what else can I feed her? And how much and how often? Once she gets solids do I still give her formula for any feedings in the day? I was googling and I was reading stuff about purée food, what is puréed though? I'm not a very good cook at all. 😩
