Before completing the following steps, you must install Kiwix-Serve on RACHEL-Pi. By default, English RACHEL-Pi does not include Kiwix, only Spanish and French RACHEL-Pi do.
Download the zim files you’d like from kiwix: http://wiki.kiwix.org/wiki/Content
Place the downloaded content into a module folder usually named by a language-descriptor format of two characters (e.g. en-wikipedia) which should have data/content/ and data/index/ subfolders inside it. (/var/www/modules/en-wikipedia)
Add to the en-wikipedia folder an index.htmlf or rachel-index.php file to add navgivation to the kiwix content on the RACHEL homepage (/var/www/modules/en-wikipedia/rachel-index.php)
Restart kiwix using the following command:
perl /var/kiwix/bin/rachel-kiwix-start.pl(or reboot the machine) – that will automatically update the kiwix library to include any newly installed kiwix modules.
