+### Deploying Trino with Apache Iceberg support
+
+To configure the Iceberg connector, create a catalog properties file like 
`etc/catalog/rest.properties` that references the Iceberg connector.
+
+```
+connector.name=iceberg
+iceberg.catalog.type=rest
+iceberg.rest-catalog.uri=http://localhost:9001/iceberg/
+fs.hadoop.enabled=true
+iceberg.rest-catalog.view-endpoints-enabled=false
+```
+
+Please refer to [Trino Iceberg 
document](https://trino.io/docs/current/connector/iceberg.html) for more 
details.
