Three day potty training method

I am going to try this with my 2 year 4 month old girl this weekend. It was kind of a last minute idea when I learned we have a three day weekend. I haven’t done too much research other than you let them be naked on their bottom half and people say it works. It is too late for any book orders but I am looking for any advice, podcasts to share or support so my husband and I can prepare for tomorrow.
