Potty Trainned Successfully

Hi mommies, can I ask at what age you will train potty for your toddler? My daughter is coming 18 months very soon so I need to prepare information and tips to face the problem when it coming. Anyone has trained potty successfully for toddler? Can share with me your tip and how to do it (like what I have to do and do how long...) I really searched internet, but all the information just talk generally...not details so I can't imagine what I should do to train her. Thank you so much ?
