How to grow mangos?

I have been thinking of getting a grafted one to keep in a pot and was wondering if there was anything special about growing them or anything you wished you done differently growing them.

Mangoes are big beautiful trees. Large trees. You want to make a bonsai? I don't know if that would produce fruit. Also it seems to me they are really quite tropical, unlike, say, citrus, which grow in places with a chilly winter. What kind of climate are you in?

I had seen online that there was a good handful of dwarf varitiys have been thinking about trying my hand with one of those. Do they comanly  get biger than 8ish foot? The plan would be for the pot to be in the yard most the year then for the month or two of cold drag it on the covered porch against the house. I'm in zone 8b so freeze at night then spikes up to 70ish. I know I'm just  smidge to far north to grow in ground or get giant harvest.
