The thing is, if you're not used to working with distributed state there's definitely a learning curve. Even simple things like incrementing a counter — the "hello world" of JavaScript framework demos — get tricky when dealing with multiple clients. Worse, a lot of tutorials are just like "install this library and text editor integration and boom you have an app", which doesn't give you a good mental model for what's actually happening.

So we made Learn Yjs! It's an interactive Yjs tutorial. I wanted it to be really intuitive for people just getting their feet wet with local-first development, so there are lots of explorable demos and coding exercises. The idea is to use interactive examples to build an understanding from the ground up.

Hope you like it :)
