How this tutorial works
The Concepts Tutorial is a collection of tutorials about the different concepts used in programming, ranging between programming style/code commenting to graphical techniques, hardware access, user input methods, and more! Within these tutorials you will find more information on the artform of programming, not just like the rules and technical stuff on the Beginner and Command tutorials.
Adding a Concept Tutorial
If you have an idea for a concept that you would like explained, please suggest your idea and we will (at least try to) write up a tutorial on that concept.
