We've created a Katacoda course featuring beginner and intermediate lessons. These allow to you try out Argo Workflows in your web browser without needing to install anything on your computer. Each lesson starts up a Kubernetes cluster that you can access via a web browser.
The course will take around 2 hours to complete and is the fastest way to learn Argo Workflows.
We also have a playlist of videos that dive into various topics. This includes contributing to Argo Workflows, not covered in the hand-on.
