+## Logging
+
+We use the standard [OkHttp logging interceptor](https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor).
+
+You can enable logging by setting the environment variable `ORB_LOG` to `info`.
+
+```sh
+$ export ORB_LOG=info
+```
+
+Or to `debug` for more verbose logging.
+
+```sh
+$ export ORB_LOG=debug
