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.
The description is slightly unclear (not bad but could have a bit more), nothing is said about the order of the sequence, which leaves you wondering if that factors in. Also, an invalid sequence is not defined, it might be worth mentioning what invalid means... at first I thought it could relate to order, or possibly multiple missing items or something.
Easy once I knew what to do.
