     <h4>Logging and Error Handling</h4>
     <p>To log any information, or report an error, the following functions are available:</p>
         <ul>
-            <li><code>node.log("Log")</code></li>
+            <li><code>node.log("Log message")</code></li>
             <li><code>node.warn("Warning")</code></li>
             <li><code>node.error("Error")</code></li>
         </ul>
     </p>
     <p>The Catch node can also be used to handle errors. To invoke a Catch node,
     pass <code>msg</code> as a second argument to <code>node.error</code>:</p>
-    <pre>node.error("Error",msg)</pre>
+    <pre>node.error("Error",msg);</pre>
     <h4>Sending messages</h4>
     <p>The function can either return the messages it wants to pass on to the next nodes
     in the flow, or can call <code>node.send(messages)</code>.</p>
