<p>Welcome to WordPress. Since you&#8217;re upgrading from b2 everything should be relatively 
  familiar to you. Here are some notes on upgrading:</p>
<ul>
  <li>If you&#8217;re using an older version of b2, it's probably a good idea to upgrade 
    to at least .61 before making the leap to WordPress.</li>
  <li>The templates are so much better, and there is so much more going on than 
    before it&#8217;s probably worth it to start from scratch and work back to your 
    design.</li>
  <li>You need to transfer some of your settings from your old <code>b2config.php</code>
    to <code>wp-config.php</code> file.</li>
  <li>WordPress issues should be discussed in our <a href="http://wordpress.org/support/">support 
    forums</a>.</li>
  <li><strong>Back up</strong> your database before you do anything. Yes, you.</li>
</ul>
<p>Have you looked at the <a href="../readme.html">readme</a>? If 
  you&#8217;re all ready, <a href="import-b2.php?step=1">let&#8217;s go</a>!</p>
