title: add dependency to scala SBT project (import play.api.libs.json.Json)
body: <p>I'm new to Scala and SBT. </p>
  
  <p>I'm following this example: <a href="https://www.playframework.com/documentation/2.1.1/ScalaJson" rel="nofollow">Play Framework</a></p>
  
  <pre><code>import play.api.libs.json.Json
  
  val json: JsValue = Json.parse("""
  { 
  "user": {
  "name" : "toto",
  "age" : 25,
  "email" : "toto@jmail.com",
  "isAlive" : true,
  "friend" : {
    "name" : "tata",
    "age" : 20,
    "email" : "tata@coldmail.com"
   }
  } 
  }
  """)
  </code></pre>
  
  <p>How do you put the dependency for this library in the build.sbt file? </p>
  
  <p>I'm using the Intellij scala IDE community edition. </p>
  
  <p>Thanks </p>
