title: How to run the Xtext .mydsl file?
body: <p>The question may seem obvious, but I'm just beginning with <code>Xtext</code>.
  So after creating the xtext project, and running the <code>mydsl.xtext</code> file.<br>
  it launches a new iteration of eclipse. I create a new  .mydsl file in a new project.  But I don't know what to do next! How do I run the <code>.mydsl</code> file??
  How do i use my <code>DSL</code>??<br>
  All Xtext tutorial stops after creating the <code>DSL</code> and don't show how to use it.
  I was following <a href="https://eclipse.org/Xtext/documentation/102_domainmodelwalkthrough.html" rel="nofollow noreferrer">the 15 minutes Xtext tutorial</a><br>
  My code is the hello word code given by eclipse, nothing really special at this point. </p>
