+[fn:7] The Pandoc Citations feature was last <2018-08-19 Sun> tested
+with Pandoc version 2.2.2. If you are running an older version, the
+quickest way to "install" might be to simply download the latest
+release archive from [[https://github.com/jgm/pandoc/releases][~Pandoc releases]], extract it and put the ~pandoc~
+and ~pandoc-citeproc~ binaries in one of the directories in your PATH.

 [fn:6] If you are still using a Hugo version older than 0.25, update
 now! -- Because that version added support for the awesome
