-It's possible to configure HyperEstraier via one of ikiwiki's
-[[templates]], but for most users, no configuration should be needed aside
-from enabling the plugin.
+This plugin adds full text search to ikiwiki, using the
+[xapian](http://xapian.org/) engine, its
+[omega](http://xapian.org/docs/omega/overview.html) frontend, and the
+[[!cpan Search::Xapian]], [[!cpan Digest::SHA]], and [[!cpan HTML::Scrubber]]
+perl modules.
+
+The [[ikiwiki/searching]] page describes how to write search queries.
+
+Ikiwiki will handle indexing new and changed page contents. Note that since
+it only indexes page contents, files copied by the [[rawhtml]] plugin will
+not be indexed, nor will other types of data files.
+
+There is one setting you may need to use in the config file. `omega_cgi`
+should point to the location of the omega cgi program. The default location
+is `/usr/lib/cgi-bin/omega/omega`.
