I think if she is ready, she will do it and their won't be any 'training' involved. Just encouraging her. But from watching my DD who will be 3 in November, she wants to do it at daycare (She is there 2 - 3 days a week).. All the other kids are going to the toilet, and she copies them. They only put a nappy on her at nap/rest time, and she has only had one accident in the last few weeks.. But at home she tends to holds it till nappy time She will go sit on the toilet, just not do anything..

But you may find, that daycare might actually be an advantage for this stage, she will do as the other kids do, and you don't get all the accidents.. Good luck..
