Zig Days are full-day, collaborative programming events.
You can learn more about this format in “Zig Day: A suggestion for better Zig meetups”.
The main goal of a Zig Day is to inspire you to make Software You Can Love.
Zig days are for collaboration and socialization. Avoid working on code you can’t collaborate on (e.g. because of its license) and try to have engaging conversations with other people.
Software You Can Love is high quality software, and the only way to make high quality software is to apply systems thinking.
Software You Can Love serves the end user. Zig Days are a great opportunity to learn how to fight against user-hostile software.
Lastly, learn some Zig.
