At 13 months, my girl was VERY interested in all things potty (she followed me every.single.time I went & watched everything I did in there)! So, we went and bought her a simple potty with lid (no music or crazy attachments) and she used it the FIRST day! From then until about 20 months she'd use it a couple of times a week (some weeks, she'd use it every day, sometimes she'd go 2 weeks not using it). I didn't pressure her, just invited her to come with me whenever I was going in there (I tried to get daddy to help, but he felt weird having her "watch" him). At her daycare, they don't start the potty until 2, so we kept this up until she moved to the 2-3 y/o class (from 20-24 months she was using it pretty much every day--and sometimes a couple of times a day). During that time, we just stuck with diapers (kept a small stack & package of wipes in the bathroom). Now that she's in the 2-3 y/o room, they use the potty all the time. After the 1st week, her teacher said that she's ready to go "all the way" and we needed to get pull-ups & underwear! She's been in that class for 4 weeks, and this week was her first full week without diapers (they wear pull-ups at naptime & I put them on her after her evening BM--before bed)!
The hardest part for me is remembering to take her to the bathroom (she can't hold it as long as I can)!
So, with all that, my advice is to just follow her lead. Invite her to go to the potty (when you go, when she gets up from bed, after meals & snacks, before bed, etc), but don't force her to go. Soon, she will get the hang of it and the Pull-ups can be used as back-up (for car trips, naptime, bedtime, etc). Even though we're currently at the brink of going diaper-less, I am still putting diapers on my girl for bedtime & long car rides (hey, I paid good money for those--I'm going to use them)! :) Good luck!
