+### Cloning SessionConfig
+
+Use `clone()` to copy a base configuration before making per-session changes:
+
+```java
+var base = new SessionConfig()
+    .setModel("gpt-4.1")
+    .setStreaming(true);
+
+var derived = base.clone()
+    .setWorkingDirectory("/repo-a");
+```
+
+`clone()` creates a shallow copy. Collection fields are copied into new collection instances, while nested objects/handlers are shared references.
+
 See [SessionConfig](apidocs/com/github/copilot/sdk/json/SessionConfig.html) Javadoc for full details.
