When you visit captrice.io for the first time, you are greeted with a form for creating a new collection.
A collection is a group of exercises. Before you can start practicing using captrice, you need to create at least one collection with one exercise.
A quicker and recommended way to get started is to import a collection from the library. Once you see an already imported collection, it should help you develop intuition for creating your own collections and exercises from scratch.
After importing a collection from the library, please read about How to practice next.
