Loading collection data...
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.

You're welcome.

Thanks for changes
No answer after a month, I've made the change myself.
Shouldn't the initial code use Double instead of Int? It adds a difficulty not present in the other translations.
Swift translation added :) Can you approve please?
