There are plenty of YouTube videos you can watch before trying it out.... make sure you watch videos using a similar size net. Trying to throw a 6 foot net with the technique a 10 foot net requires may not go well.
That being said, there are several different techniques used to get the same result; you'll find one that works for you and it shouldn't take more than 15 minutes to get it consistently. I always practice right on the lawn every early spring as a refresher.
I definitely would watch some videos before trying though, if it is totally new to you...
