Lottie

I am trying to learn how to use Lotties. The Lottie website is very hard to understand, and I cannot find tutorials. I was able to create a Lottie, but they use < > characters in the code that says it will break the theme. Are there instructions to change the code and still have the Lottie work?

This may be too hard and ready to give up. I see there is one lottie available in the Enfold theme to use. I wish there were more.

Or any other instuctions on lotties would be helpful.

Thanks for your help
