20 -# USAGE: once FeedWordPress is installed, you manage just about everything from
21 -# the WordPress Dashboard, under the Syndication menu. To ensure that fresh
22 -# content is added as it becomes available, you can convince your contributors
23 -# to put your XML-RPC URI (if WordPress is installed at
24 -# <http://www.zyx.com/blog>, XML-RPC requests should be sent to
25 -# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the
26 -# Syndication menu, or set up automatic updates under Syndication --> Settings,
27 -# or use a cron job.
