I was clueless when I started with Andie, too, but here's how we did it:
We had a potty chair in the bathroom, so she was familiar with it before we even started. I began "talking it up", and one day we went out & bought her the big-girl panties PLUS her "reward"....candy, as she has a sweet tooth just like her mommy!

She picked out Hershey Kisses, and when we got home I put them in one of my pretty crystal bowls and put them in a VERY prominent place on the vanity in the bathroom. She knew she would get one whenever she used the bathroom on the potty.
I also had a little "bathroom bag" with new fun stuff in it like bubbles, books, a doll....stuff she ONLY could play with while she was sitting on the potty trying to go.
The day we started, I ditched the diapers (used pull-ups for nap & night). I set the timer for 30 minutes initially, but that was too long (I wanted to be sure she had accomplishments in the beginning rather than failures), so I backed it to 20 minutes, & we'd go sit on the potty every 20 minutes without fail. Then after a couple days, I bumped it up to 25 min, then 35....etc.
It only took maybe a week & a half before she was daytime potty trained. Not too many accidents, mainly when she got busy playing and just didn't think about it...
Good luck! I know you'll get a bunch of good tips...just gotta keep trying until you find something that will work for your daughter....
