+# Configuring SASL
+
+You can either configure SASL through `!serverset sasl` from an registered and identified admin account or directly through sqlite.
+
+## USERPASS Mechanism
+
+BitBot supports a special SASL mechanism name: `USERPASS`. This internally 
+represents "pick the strongest username:password algorithm"
+
+## !serverset sasl
+
+These commands are to be executed from a registered admin account
+
+#### USERPASS
+> !serverset sasl userpass &lt;username>:&lt;password>
+
+#### PLAIN
+> !serverset sasl plain &lt;username>:&lt;password>
+
+#### SCRAM-SHA-1
+> !serverset sasl scram-sha-1 &lt;username>:&lt;password>
+
+#### SCRAM-SHA-256
+> !serverset sasl scram-sha-256 &lt;username>:&lt;password>
+
+#### EXTERNAL
+> !serverset sasl external
+
+## sqlite
+
+Execute these against the current bot database file (e.g. `$ sqlite3 databases/bot.db`)
+
+#### USERPASS
+> INSERT INTO server_settings (&lt;serverid>, 'sasl', '{"mechanism": "userpass", "args": "&lt;username>:&lt;password>"}');
+
+#### PLAIN
+> INSERT INTO server_settings (&lt;serverid>, 'sasl', '{"mechanism": "plain", "args": "&lt;username>:&lt;password>"}');
+
+#### SCRAM-SHA-1
+> INSERT INTO server_settings (&lt;serverid>, 'sasl', '{"mechanism": "scram-sha-1", "args": "&lt;username>:&lt;password>"}');
+
+#### SCRAM-SHA-256
+> INSERT INTO server_settings (&lt;serverid>, 'sasl', '{"mechanism": "scram-sha-256", "args": "&lt;username>:&lt;password>"}');
+
+#### external
+> INSERT INTO server_settings (&lt;serverid>, 'sasl', '{"mechanism": "external"}');
