	<h2>Link Adder Settings</h2>
	<p>Settings to customize the plugin will come in future versions of Link Adder. You will then also be able to choose which category the link ends up in. Until then, the link will be assigned to the default category.</p>
	<p>The code in this bookmarklet has been customized specifically for your WordPress install, so it will not work for any other site.</p>
	<h3>Add Bookmarklet</h3>
	<p>Drag the link below to your bookmarks, or right click on the link and choose Bookmark This Link.</p>
