 		<h3>Tips</h3>
 		<ul>
 			<li>Put 2 spaces at the end of a line to add a soft line break. Leave a blank line to add a head line break (i.e. a new paragraph).</li>
-			<li>You can add an id to a header that you can link to. Put it in curly braces after the heading name like this: <code># Heading Name {#HeadingId}</code>. Then you can link to like like this: <code>[[Page name#HeadingId}]]</code>. You can also link to a heading id on the current page by omitting the page name: <code>[[#HeadingId]]</code>.</li>
+			<li>If you don't like the default id given to a header, you can add a custom one instead. Put it in curly braces after the heading name like this: <code># Heading Name {#HeadingId}</code>. Then you can link to like like this: <code>[[Page name#HeadingId}]]</code>. You can also link to a heading id on the current page by omitting the page name: <code>[[#HeadingId]]</code>. Finally, a heading id is automatically generated for every heading by default. Take the heading name, make it lowercase, and replace the spaces with dashes <code>.</code>, and that's the heading ID that you can link to (although sometimes some special characters are removed).</li>

 		<h3>Extra Syntax</h3>
 		<p>$settings->sitename's editor also supports some extra custom syntax, some of which is inspired by <a href='https://mediawiki.org/'>Mediawiki</a>.
