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.
Unless you forbid the native method, this is too thin a wrapper to make a kata.
Also, do a search and see if this hasn't been done before. My guess is it has, but I'm too lazy to do your job.
