How do i properly cut a mango?

How do I properly cut a mango and is the peeling ok to eat and what would the peeling do to your body?

The peel is ok but a little hard to digest... I'd rather toss it.

The way I was taught to cut a mango is lengthways into three, so the large seed is the middle third, Then with a sharp knife, score the existing bits into squares... so that when you pop it inside out, all the squares stand out and you can bite them off. I'm sure there's a simpler way to say this but I can't think, LOL.
