<p>With the Pronamic Domain Mapping plugin you can easily publish a page on the domain aliases or pointers of your hosting solution. This way you can easily publish landing pages on the extra domain names you own.</p>
<h4>WordPress Network</h4>
<p>If you work with an WordPress Network and want to enable domain pages you have<br />
to add the following line to your /wp-content/sunrise.php file.</p>
<pre><code>$file = WP_CONTENT_DIR . '/plugins/pronamic-domain-mapping/sunrise.php'; 

if ( is_readable( $file ) ) {
    include $file;
}
</code></pre>
