+This is a very vanilla image of DokuWiki following the official instructions as closely as I can pay attention...
+
+
+## Important Reminder
+
+Make sure that once you've completed installing DokuWiki through your browser at `yourdomain.tld/install.php` that you uncomment out the `location ~ /(conf/|bin/|inc/|install.php) { deny all; }` line in the nginx config.
