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.
Get started now by creating a new collection.

That is not the way to do a description, initial code, example tests or submit tests.
Do everybody including yourself a favour and unpublish this, read available documentation on publishing your first kata and then create something better ( and more original ). This is only going to cost you points.
