title: How to manage story points when there are a number of tasks?
body: <p>I am trying to get my head around how story points are assigned to sub tasks and how the story points are managed in Jira. </p>
  
  <p>I have a user story which we have estimated at 25 points.
  A developer will take this user story and split it up in to a number of tasks.</p>
  
  <p>Should he allocate a number of story points (of the 25) to each task? So in all, all tasks should add up to 25 points? And if the user closes a task of 10 story points, will Jira know that 10 story points have been burned from the main user story of 25 points?</p>
  
  <p>Also, if at the end of the sprint the user story is not complete (say only 20 points have been completed), do I create a new user story of 5 points in the next sprint? </p>
