+;   Only use this if you allow short URL creation without credentials.
+; - Alternatively, using the parameters in this section ("signature" and
+;   "apiurl"), "urlshortener" needs to point to the base URL of your PrivateBin
+;   instance with "?shortenviayourls&link=" appended. For example:
+;   urlshortener = "${basepath}?shortenviayourls&link="
+;   This URL will in turn call YOURLS on the server side, using the URL from
+;   "apiurl" and the "access signature" from the "signature" parameters below.
