 * IP address and netmask to `include/netif.h`
 * IP address to `include/rtps/config.h`
 
+Alternatively, you can use the provided `update_ip.sh` script to automatically update these files according to your building environment. 
+The `update_ip.sh` script is designed to overwrite the IP address and netmask in `include/rtps/config.h` and `include/netif.h` files based on the current network configuration.
+
+To use the script, make it executable and run it:
+
+   ```bash
+   chmod +x update_ip.sh
+   ./update_ip.sh
+   ```
+
+This script retrieves the current IP address and netmask of the system's active network interface and updates the specified files accordingly.
+Make sure to check the output to ensure the updates are correct before proceeding with the build.
+If multiple network interfaces are available, ensure the correct one is being used.
+
+For troubleshooting, verify that the script runs without errors.
+If you encounter issues, check that the necessary network tools are installed and that your system has an active network connection.

+## mros2 Directory Overview
+
+The `mros2` directory contains several test programs and configuration files, which are actively used in the CI testing process. Below is the structure and overview of the this directory:
+
+```
+mros2/
+├── docker-compose.yml
+├── test_echoback_string
+├── test_echoback_string_responder
+├── test_echoback_twist
+└── test_echoback_twist_responder
+```
+
+- **docker-compose.yml**: This is an experimental file that was prepared for setting up the environment, but it is currently not used in the CI process. See `.github/workflows/humble_docker_test.yaml`
+
+- **test_echoback_string**: A test program that sends a string message and expects an echo response, validating communication for string messages in a ROS 2 environment. It is designed to communicate with the `mros2-host-example`'s `mros2_echoreply_string` (a test for Native ROS) and `test_echoback_string_responder` (a test for mROS). The responder listens for incoming messages and sends back the received message.
+
+- **test_echoback_string_responder**: This program subscribes to incoming string messages and echoes them back, facilitating the echo test for string messages.
+
+- **test_echoback_twist**: A test program that sends a `geometry_msgs::msg::Twist` message and expects an echo response, validating communication for Twist messages in a ROS 2 environment. It communicates with the `mros2-host-example`'s `mros2_echoreply_twist` (a test for Native ROS) and `test_echoback_twist_responder` (a test for mROS).
+
