+================
+Scylla connector
+================
+
+The Scylla connector allows querying data stored in
+`Scylla <https://www.scylladb.com//>`_.
+
+Requirements
+------------
+
+To connect to Scylla, you need:
+
+* Scylla version 3.0.0 or higher.
+* Network access from the Trino coordinator and workers to Scylla.
+  Port 9042 is the default port.
+
+Configuration
+-------------
+
+To configure the Scylla connector, create a catalog properties file
+``etc/catalog/scylla.properties`` with the following contents,
+replacing ``host1,host2`` with a comma-separated list of the Scylla
+nodes, used to discovery the cluster topology:
+
+.. code-block:: text
+
+    connector.name=scylla
+    cassandra.contact-points=host1,host2
+
+You also need to set ``cassandra.native-protocol-port``, if your
+Scylla nodes are not using the default port 9042.
+
+Compatibility with Cassandra connector
+--------------------------------------
+
+The Scylla connector is very similar to the Cassandra connector with the
+only difference being the underlying driver.
+See :doc:`Cassandra connector <cassandra>` for more details.
