Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

I kept the sentence in the description though. Mainly for the case when you pass an empty array. I believe it helps to understand what is expected in that specific case.
Great, thank you!
