Using what you've just learned, specify a new path, operation, and operation object for the Create User endpoint, filling in the tags, summary, description, and responses properties. You should end up with something like this:

paths:
  /users:
    post:
      tags:
        - Users
      summary: Creates a New User
      responses:
