 following it. Thus, if you want to make a <code>RewriteCond</code> apply
 to several <code>RewriteRule</code>s, one possible technique is to
-negate those conditions and use a [Skip] flag. So, you can
+negate those conditions and add a <code>RewriteRule</code> with a [Skip] flag. You can
 use this to make pseudo if-then-else constructs: The last rule of
 the then-clause becomes <code>skip=N</code>, where N is the
-number of rules in the else-clause.</p>

+RewriteCond %{REQUEST_FILENAME} !-f<br />
+RewriteCond %{REQUEST_FILENAME} !-d<br />
+# Create an if-then-else construct by skipping 3 lines if we meant to go to the &quot;else&quot; stanza.<br />
