in this first section of the tutorial we talk about the basics of the uxn computer called varvara, its programming paradigm in a language called uxntal, its architecture, and why you would want to learn to program it.
we also jump right in into our first simple programs to demonstrate fundamental concepts that we will develop further in the following days.

# day 3
here we introduce the use of the controller device in the varvara uxn computer: this allows us to add interactivity to our programs, and to start implementing control flow in uxntal.
we also talk about logic and stack manipulation instructions in uxntal.

stay tuned!
