Setup

This program was written in a Linux environment, for the Linux environment. Therefore if you use Windows you should install WSL2 and a Linux distribution (I tested it on Ubuntu Preview). I don't think it can work on MacOS, but you're free to try, and anyway it would not be too difficult to make it work there in the future.

Install zig

First thing, you need Zig itself. If you don't have it, or if you have a different version installed, you can download it here. Currently this document uses the 0.15.1 release, so it's the one that you should download.

Decompress the archive somewhere, for example in ~/.local/zig:

tar xf <archive> --directory=/home/username/.local
mv <name-of-extracted-directory> zig

Then add this directory to your path by adding this to your .bashrc

export PATH=$PATH:~/.local/zig

Now start a new terminal instance and see if zig is in your path:

zig version

And it should print

0.15.1

Finally, choose a directory for your project and initialize it:

mkdir kilo-zig
cd kilo-zig
zig init
