When you finished reading the Getting Started section, you're ready to pick up an idea and make it a Plus! Live script.
This will mean a lot of trial and error, I can assure you that. Think about something you want to try out, then think how you'd convert that idea into code. It really depends on what you want to do, it's impossible to give an all-round solution for each possible idea. Try to come up with something interesting which you might find useful, and then be creative. It may help if you already have some programming experience, if not you might run into difficulties understanding the thinking process of writing a program.
If you ever need help with how to execute a certain idea, don't hesitate to ask here. We'll see if your idea is technologically possible with the current possibilities of the scripting engine and help you with finding a good approach for your code. Just try to avoid asking for completely functioning code - you'll learn much more when you write your code
yourself!
