21	27	# USAGE: once FeedWordPress is installed, you manage just about everything from
22		-# the WordPress Dashboard, under Options --> Syndication or Links --> Syndicated
23		-# To ensure that fresh content is added as it becomes available, get your
24		-# contributors to put your XML-RPC URI (if WordPress is installed at
25		-# <http://www.zyx.com/blog>, XML-RPC requests should be sent to
26		-# <http://www.zyx.com/blog/xmlrpc.php>), or see `update-feeds.php`
	28	+# the WordPress Dashboard, under the Syndication menu. To keep fresh content
	29	+# coming in as it becomes available, you'll have to either check for updates
	30	+# manually, or set up one of the automatically-scheduled update methods. See
	31	+# <http://feedwordpress.radgeek.com/wiki/quick-start/> for some details.
