User stories are a technique used in agile development to capture a description of a feature from an end-user's perspective. They are typically written in a simple, structured format: "As a [type of user], I want [some goal] so that [some reason]." This approach helps to ensure that the development team is building features that are useful and valuable to users.
Example
"As a frequent shopper, I want to be able to save my payment information so that I can checkout more quickly and easily in the future.”
