This guide is intended to provide a simple introduction to the syntax and structure of programs written in Ripley. It's important to note, however, that Ripley is an experimental implementation of a language, and not a language intended for production code.
The User's Guide is divided into chapters which follow how you might learn the language if you just started with an editor and the interpreter. As you might expect, the first thing to learn is how to "Printing things out", so that you can see what you are doing. After that you might want to learn how to "Do some math". This section will also teach you about the basic nature of Ripley, about the operand and execution stacks.
After print stuff out and doing some math, you will probably want to create some "Variables". Next, we modularize with "Making New Functions". After learning how to store stuff in memory and modularize, then next step would be to make decisions based on it, you will learn how to do that in "Ifs and Elses". Finally we loop and iterate over arrays using "Loops and stuff".
