+=head1 SASL Auth
+
+=head2 Description
+
+=over
+
+This module adds support for IRCv3 SASL authentication, a nicer way of authenticating
+to services and/or the IRCd.
+
+SASL is available in Charybdis IRCd's and InspIRCd 1.2+ with m_cap and m_sasl. Atheme
+IRC Services also allows you to identify to NickServ/UserServ with SASL.
+
+=back
+
+=head2 How To Use
+
+=over
+
+To use SASLAuth, first add it to module auto-load then add the following to the server
+block(s) you wish to use SASL with:
+
+sasl_username "services accountname";
+sasl_password "services password";
+sasl_timeout <timeout in seconds>;
+
+=back
+
+=head2 Examples
+
+=over
+
+sasl_username "JohnBot";
+sasl_password "foobar12345";
+sasl_timeout 20;
+
+=back
+
+=head2 To Do
+
+=over
+
+* Add support for SASL mechanism DH-BLOWFISH.
+
+=back
+
+=head2 Technical
+
+=over
+
+This adds an extra dependency: You must build Auto with the --enable-sasl option.
+
+THis module is compatible with Auto v3.0alpha1+.
