title: How to setup TFS 2013 build definition to build from Git tag?
body: <p>I want to create a special build definition in TFS 2013 to build from tag. The source control used in that project is Git.</p>
  
  <p>So, let's say I have a tag called <code>v1.0</code>. I want this build definition to pull the sources corresponding to that tag and run a build. Triggers don't matter for now - it could be even manual. How is that possible?</p>
  
  <p>I can see you only have an option to choose branch on the Source Settings tab...</p>
  
  <p>Consider the advanced scenario: a build is triggered when a new tag is created, and takes the sources from that newly created tag to run a build. Is that possible? If so, how?</p>
  
  <p>I failed to find any information besides plain default scenarios explained on MSDN. Probably, because the configuration (TFS 2013 in Git mode) is quite new...</p>
  
  <p>Thanks in advance.</p>
