 This is the default runtime used within OpenHands.
 
+### Local Runtime
+
+The Local Runtime is designed for direct execution on the local machine. Currently only supports running as the local user:
+
+- Runs the action_execution_server directly on the host
+- No Docker container overhead
+- Direct access to local system resources
+- Ideal for development and testing when Docker is not available or desired
+
+Key features:
+- Minimal setup required
+- Direct access to local resources
+- No container overhead
+- Fastest execution speed
+
+**Important: This runtime provides no isolation as it runs directly on the host machine. All actions are executed with the same permissions as the user running OpenHands. For secure execution with proper isolation, use the Docker Runtime instead.**
+
 ### Remote Runtime
 
 The Remote Runtime is designed for execution in a remote environment:
