Go to #raku (irc.libera.chat) and someone will be glad to help you get started.
Every language has its own way of doing things. Raku is no different. Our mentors will help you learn to think like a Raku developer and how to write idiomatic code in Raku. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Raku - they'll help you discover the things you don't know that you don't know.
