I'm not the 'train them in 2/3/4 days flat' type, I see it as more of a process - like weaning. So, maybe this isn't what you're looking for, but, this is what I'd do...
I'd wrap it up and make a big fuss of her opening it. Tell her it's for wees and poos and let her just play with it for a few days (sit her dolls and toys on it etc). Make sure she know you go to the toilet, let her come with you and talk about it too. If you know any older children who could demonstrate potty use that would be fab!
Other than that, when she's familiar with it, I'd sit her on it at nappy changes. Most children wee when thye've just woken up so I'd try and 'catch' some wee that way too, just so she gets the idea. If you make a 'psss' sound when she wees you can use it as a cue when you want her to go.
Give her plenty of nappy free time to have the opportunity to use it. There will be accidents but IMHO that's a good thing, as long as you remain cool and calm it helps them get the idea
DD has had (and used) a potty since about 9 months old and at 20 months she's now dry at home. She still has nappies for naps and outings but they stay dry more and more often so I think it's nearly time for the next step.
Good luck!
