+    Step 3: Build
+  </summary>
+
+1. Before starting building of our packages, make sure you have OpenCV for Windows installed on your machine. If you choose the Microsoft IOT way to install it, it will be installed automatically. Later, when colcon build, you might need to expose this installation folder by setting CMAKE_PREFIX_PATH, PATH, or OpenCV_DIR environment variables
+2. Run "x64 Native Tools Command Prompt for VS 2019" as administrator
+3. Setup ROS2 Environment (Do this for every new terminal/cmd you open):
+    - If you choose the Microsoft IOT Binary option for installation
+      ```
+	  > C:\opt\ros\humble\x64\setup.bat
+	  ```
+	
+    - If you choose the ROS2 formal documentation:
+      ```
+	  > call C:\dev\ros2_iron\local_setup.bat
+	  ```   
+4.  Change directory to realsense-ros folder
+      ```bash
+      > cd C:\ros2_ws\realsense-ros
+      ```
+5. Build librealsense2 package only
+      ```bash
+      > colcon build --packages-select librealsense2 --cmake-args -DBUILD_EXAMPLES=OFF -DBUILD_WITH_STATIC_CRT=OFF -DBUILD_GRAPHICAL_EXAMPLES=OFF
+      ```
+	  - User can add `--event-handlers console_direct+` parameter to see more debug outputs of the colcon build
+6. Build the other packages
+	```bash
+	> colcon build --packages-select realsense2_camera_msgs realsense2_description realsense2_camera
+	```
+	- User can add `--event-handlers console_direct+` parameter to see more debug outputs of the colcon build
+
+7. Setup environment with new installed packages (Do this for every new terminal/cmd you open):
+      ```bash
+      > call install\setup.bat
+      ```
