-If you're installing MarkDown by hand, note that it should be installed as
-`Markdown.pm` somewhere in perl's module search path, or alternately as
-`/usr/bin/markdown`. Ikiwiki will find it under either name.
+It also uses the following perl modules if available: [[cpan
+CGI::Session]], [[cpan CGI::FormBuilder]] (version 3.05 or newer), [[cpan
+Mail::Sendmail]], [[cpan Time::Duration]], [[cpan TimeDate]], [[cpan
+HTML::Scrubber]], [[cpan RPC::XML]], [[cpan XML::Simple]], [[cpan
+XML::Feed]], [[cpan File::MimeInfo]], [[cpan Locale::gettext]] (version
+1.04 or newer).
+
+It's recommended you have a C compiler, as ikiwiki uses one to build
+wrappers.
+
+Various [[plugins]] use other libraries and utlities; see their individual
+documentation for details.
+
+The Debian packages depend on and recommend an appropriate set of packages.
+
+While Fedora 7 doesn't have an ikiwiki package, you can install needed
+perl modules using this command:
+
+ yum install perl-Text-Markdown perl-Mail-Sendmail perl-HTML-Scrubber \
+ perl-XML-Simple perl-TimeDate perl-HTML-Template perl-CGI-FormBuilder \
+ perl-CGI-Session perl-File-MimeInfo perl-gettext
