+<h2>A word of warning</h2>

+Please note that, especially for new Icecast users, editing the config file can be quite tricky. <strong>It is thus recommended to start by just changing all passwords, nothing else.</strong> You can then use the source-password to bring up an initial stream and get more comfortable with how Icecast works.

+<p>
+Should you need to customize the configuration, then make a backup of your working config file, before you make any changes. If Icecast refuses to start it is in most cases due to a malformed config file. In such a case running the following command should point out most XML syntax problems.
+<pre>xmllint icecast.xml</pre>
+Also check the Icecast error.log for additional hints.
