A user story artifact captures a description of a software feature from an end-user perspective, effectively creating a simplified description of a requirement.
User stories are typically auto-generated from the details of tasks and system tasks in a process in Storyteller to ensure high-quality, consistent user stories. However, they can be created manually if required. User stories also have their own relationships, discussions, files, and history.
For more information regarding generating user stories, see the Generate User Stories article.
