You can add stories to the backlog using either the Quick Story or Detailed Story options.
There are two ways to add stories to the backlog:
Add stories quickly in the backlog
It's easy to quickly add stories directly to your backlog to capture an idea and then follow up later to provide actionable ideas. An example of a Quick Story would be "As a user, I want to be able to add an avatar to my user profile."
Add detailed stories in the backlog
When you have a good idea of details you want to include to make a story complete. You can add tasks, attachments, images, and rich text while creating a story. An example of a detailed story would be ""As a user, I want to be able to add an avatar to my user profile" with a wireframe attachment of how you want the interface to look in the UI along with specifications of what types of graphics can be used and the size of files that can be uploaded.
