title: How to migrate to Gatling 2.2 from 2.1.7
body: <p>I'm not really good with Scala and I really want to love Gatling, but lack of documentation makes it really difficult.
  Here is the problem that I've encountered after trying to migrate to 2.2.0 version from 2.1.7:</p>
  
  <ul>
  <li><strong>global</strong> - now requires GatlingConfiguration for some reason, could someone provide example of how to use it with latest version?</li>
  <li><strong>throttling</strong> - now should be added via some sort of ThrottlingSteps -as before, could someone give me example how to use it correctly?</li>
  </ul>
  
  <p>Worst part of this madness is that on official Gatling website <a href="http://gatling.io/docs/2.2.2/migration_guides/2.1-to-2.2.html" rel="nofollow">migration article</a> doesn't cover this part and <a href="http://gatling.io/docs/2.2.2/general/assertions.html?highlight=assertions" rel="nofollow">official documentation</a> is obsolete </p>
