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.
