User stories in Agile development are collected to describe high-level user requirements.
Step-by-step explanation:
In Agile development, user stories are collected to describe high-level user requirements. User stories are short descriptions of a desired feature or functionality from the perspective of the end user. They are usually written in the format 'As a [role], I want [goal], so that [reason]'. For example, a user story could be 'As a user, I want to be able to change my password via a mobile app, so that I can keep my account secure.'
