title: Understanding project structure when using SBT project in Intellij Idea
body: <p>When I create a SBT Scala project with Intellij Idea 14.0.3, I end up with the following project structure:</p>
  
  <p><img src="https://i.stack.imgur.com/3LolG.png" alt="newly created project"></p>
  
  <p>The problem is, src folder is under the project root and then there is the project node at the same level (highlighted in the screenshot)</p>
  
  <p>I could not find any documentation that explains this layout and it is very confusing. I've managed to compile and deploy scala apps but what is that project node doing? What use do I have for it? What artefacts, if any are supposed to go under it? </p>
