I have never used GitHub and I only really know a small bit about Java programming. I would like to start learning to code so I can make a branch (I hope the terminology is right) of https://github.com/n8willis/celtx this open source software (Celtx). I really liked the program and don’t really like the online version at all.
My question is what compiler do I use to open it / modify it? I have used Netbeans for the small projects like hello world and variable introductions; but when I open this it doesn’t do anything correctly. Am I even using the correct program to code with?
