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.

2032 -# feeds to syndicate. "Contributors" is the category used by default; you can
2033 -# configure that under Options --> Syndication.

2035 -# Fields used are:
2036 -#
2037 -# * link_rss: the URI of the Atom/RSS feed to syndicate
2038 -#
2039 -# * link_notes: user-configurable options, with keys and values

2041 -#
2042 -# key: value
2043 -# cats: computers\nweb
2044 -# feed/key: value
2045 -#
2046 -# Keys that start with "feed/" are gleaned from the data supplied
2047 -# by the feed itself, and will be overwritten with each update.
2048 -#
2049 -# Values have linebreak characters escaped with C-style
2050 -# backslashes (so, for example, a newline becomes "\n").
2051 -#
2052 -# The value of `cats` is used as a newline-separated list of
2053 -# default categories for any post coming from a particular feed.
2054 -# (In the example above, any posts from this feed will be placed
2055 -# in the "computers" and "web" categories--*in addition to* any
2056 -# categories that may already be applied to the posts.)
