-	<description>Provide WebFinger for all users so they get a user address like user@owncloudinstance which can be used for unhosted applications. If you don't run ownCloud in the root of your domain, for instance if you run it on example.com/owncloud/, then make sure you link example.com/.well-known/ to example.com/owncloud/apps/user_webfinger/ - by running something like "ln -s /var/www/owncloud/apps/user_webfinger /var/www/.well-known". Only enable this app if you run this ownCloud installation on a public web address, not if you run it on an intranet or on localhost.</description>

+/**
+ * To include your app in the webfinger XML, add a new script with file name
+ * 'webfinger.php' to /apps/yourapp/appinfo/, which prints out the XML parts
+ * to be included. That script can make use of the constants WF_USER (e. g.
+ * "user"), WF_ADDRESS ("user@host") and WF_ROOT ("https://host/owncloud").
+ * An example could look like this:
+ * 
+ * <Link
+ * 	rel="myProfile"
+ * 	type="text/html"
+ * 	href="<?php echo WF_ROOT; ?>/apps/myApp/profile.php?user=<?php echo WF_USER; ?>">
+ * </Link>
+ *
+ '* but can also use complex database queries to generate the webfinger result
