+### Using a SOCKS5 Proxy
+
+To run the integration test via a SOCKS5 proxy, you need to set the environment variable `SOCKS_PROXY`. The following
+command requires a running proxy on the local machine.
+
+```console
+$ KAFKA_CONNECT=0.0.0.0:9011,kafka-1:9021,redpanda-1:9021 SOCKS_PROXY=localhost:1080 cargo test --features full
+```
+
+The SOCKS5 proxy will automatically be started by the docker compose files. Note that `KAFKA_CONNECT` was extended by
+addresses that are reachable via the proxy.
+
 ### Java Interopt
 To test if RSKafka can produce/consume records to/from the official Java client, you need to have Java installed and the
 `TEST_JAVA_INTEROPT=1` environment variable set.
