This tutorial will take you step by step through the arr.ai language. It will be light on theory, focusing more on learning by doing. If you want a more theoretical introduction to the features of the language, Introduction to Arr.ai is a good place to start.
The following chapters start with the basics of the language, and develop steadily towards the more advanced features.
To follow along, use arr.ai's interactive shell, which may be started with:
$ arrai i
@> _or, if an appropriate symlink is set up (see the main README for instructions):
$ ai
@> _Once you see the @> prompt, you can try the code examples in the following
chapters.
