title: Where are the definitions for Azure Boards work item types?
body: <p>Azure DevOps currently supports 4 different project processes. One example of a project process is Agile. <a href="https://docs.microsoft.com/en-us/azure/devops/boards/work-items/guidance/agile-process?view=azure-devops" rel="nofollow noreferrer">Within the Agile process</a>, Azure Boards supports several different work item types such as <code>Epic</code>, <code>Feature</code>, <code>User Story</code>, <code>Bug</code>, <code>Task</code>, <code>Issue</code>, etc. I would like to use Azure Boards and the work item types but don't have an understanding of the types, exactly what they mean, and the difference between each type. </p>
  
  <p>Where are the formal definitions of these types, and any examples of a use for each work item type?</p>
