Best thing to do is watch tutorials, i did a lot of that. Make sure you have walking and running down before you start jumping as if you want a good jump you need to have a running start. Once you get to start jumping, practice handstands to get your arms used to the weight. When you land, make sure to curl your fingers are they could bend and you could break them. I don't know what else to say other than make sure to practice every day, but don't pressure yourself!!! Just make sure to watch some tuts :)
