+
+Certificate validation in Limnoria
+----------------------------------
+
+Until version 2016.02.24, Limnoria did not support certificate validation.
+Starting from this version, it is possible, but disabled by default, in order
+to not break existing bot when updating.
+
+Certificate validation can be enabled using this command::
+
+    @config supybot.protocols.ssl.verifyCertificates true
+
+Available validation mechanisms are Certification Authorities and
+fingerprint checking.
