-## Deploying Zenoh on Multiple Raspberry Pi Devices Using Docker
+## Deploying Zenoh on Multiple Raspberry Pi Devices
 
 After building Zenoh and its core examples, your next step is to deploy them across multiple Arm-based devices. 
 
-In this section, you’ll use Raspberry Pi boards to simulate a scalable, distributed environment, but the same workflow applies to any Arm Linux system, including Arm cloud instances.
+Once you’ve successfully installed Zenoh on an Arm Cortex-A or Neoverse platform in the previous session, you can either transfer the compiled binaries from `~/zenoh/target/release/` to your Raspberry Pi devices, or use Docker to quickly deploy them across multiple RPi nodes.
 
-You’ll learn how to use Docker to deploy the environment on physical devices.
+In this session, you’ll use Raspberry Pi boards to simulate a scalable, distributed environment—but the same workflow applies to any Arm Linux system, including Arm cloud instances and Arm Virtual Hardware.
 
 This setup lets you simulate real-world, cross-node communication, making it ideal for validating Zenoh's performance in robotics and industrial IoT use cases.

 To simplify this process and ensure consistency, you can use Docker to containerize your Zenoh and ROS 2 environment. 
 This lets you quickly replicate the same runtime on any device without needing to rebuild from source.

+To ensure compatibility with ROS-related tools, create a `Dockerfile` based on  `ros:galactic `, and use the official Rust installation method to build Zenoh, as shown below.

+In the second stage, it installs essential ROS 2 demo tools and copies the Zenoh executables into the final runtime image.
