 By default, this adds hyperlinks for several parts of ripgrep output: the
-per-file header, match context lines, and match lines. Passing the 
+per-file header, match context lines, and match lines. You can control which
-`--hyperlink-only-matches` flag will only add hyperlinks to the match lines.
+items are linked with a :command:`--kitten hyperlink` flag. For example,
+:command:`--kitten hyperlink=matching_lines` will only add hyperlinks to the
+match lines. :command:`--kitten hyperlink=file_headers,context_lines` will
+link file headers and context lines but not match lines.
+:command:`--kitten hyperlink` may be specified multiple times.
 
 Hopefully, someday this functionality will make it into some `upstream grep
