title: Where can I find MongoDB 2.0 documentation / manual
body: <p>I have MongoDB 2.0 version running in the production on some servers. I'm currently unable to upgrade them to 2.2 or 2.4 for various reasons, but I'm planning to do it in the future.</p>
  
  <p>On mongodb.org there are only 2.2 and 2.4 versions of the documentation. Where can I find the 2.0 documentation?</p>
