title: How to use VS Code as merge and diff tool in SourceTree?
body: <p><a href="https://stackoverflow.com/questions/46770156/visual-studio-code-for-mac-as-diff-merge-tool-in-sourcetree">This question</a> and some others discuss how this could work on a Mac, but I couldn't find documentation from Microsoft or Atlassian on a way to do this on Windows <em>without</em> trying to make it the global Git setting. (I just prefer to change things within the IDE where possible.)</p>
  
  <p>What are the parameters to use with the "Custom" settings in SourceTree's "Options" dialogue "Diff" tab, for diff'ing and merging with VS-Code?</p>
