 <h2>Why is this an issue?</h2>
-<p>When defining custom attributes, <code>System.AttributeUsageAttribute</code> must be used to indicate where the attribute can be applied. This will
-determine its valid locations in the code.</p>

+<p>When defining custom attributes, <a href="https://learn.microsoft.com/en-us/dotnet/api/system.attributeusageattribute">AttributeUsageAttribute</a>
+must be used to indicate where the attribute can be applied. This will:</p>
+<ul>
+  <li> indicate how the attribute can be used </li>
