+  <p>{{generic-specific-explanation-p2 We classify a filter to be <strong>specific</strong> if it matches one or more domains or matches a sitekey. If a filter has no domains specified (or only domain exceptions) and no sitekey then it counts as <strong>generic</strong>. For example <code><fix>example.com##div.textad</fix></code> is a specific filter, where as both <code><fix>##div.textad</fix></code> and <code><fix>~example.com##div.textad</fix></code> are generic.}}</p>
+  <p>{{generic-specific-explanation-p3 Note that with blocking rules the domain must be specified under the $domain option for them to be considered specific. For example <code><fix>||example.com^</fix></code> is considered generic whereas <code><fix>*/ads/*$domain=example.com</fix></code> is site-specific.}}</p>
