Definition of User Story:
A user story is a short, non-technical statement of a product requirement written from the user’s point of view. A user story is usually written according to the following structure:
“As a <type of user>, I want to <perform some task> so I can <achieve some goal.>”
Use of User Stories:

The team members assign story points to each story to estimate the effort needed to finish the individual stories, and break them down into tasks to be completed during the sprint. When the iteration or sprint is completed, the team should have produced a functional product or deliverable that corresponds to the initial requirement specified in the story.
