 - Once you have updated the launch file, build the code again using `colcon build --packages-select yolov3_ros` and proceedas mentioned below.
 
 Steps to run:
-1. Open a terminal.
-2. Run `$ cd greenhouse/ros2_ws/` and `$ . install/setup.bash`.
-3. Launch node for object detection:
+- Open a terminal.
+- Run `$ cd greenhouse/ros2_ws/` and `$ . install/setup.bash`.
+- Launch node for object detection:
 ```
 $ ros2 launch yolov3_ros pipe_detection.launch.py
 ```
 This node will output two topics: `/bboxes` and `/detection_image`.
-4. Launch node for pose estimation:
+Make sure that you run this launch file from `greenhouse/ros2_ws/` folder since the path of weights is relative (`/src/pipe_weights.pt`) inside the launch file.
+- Launch node for pose estimation:
 ```
 $ ros2 launch find-pose find-pose-node.launch.py
 ```
 This node will output TF topics between `/camera_link` and `/${detected_object_name}`.

-5a. Go to `Add` button. Under `By Display type`, select `tf`. Once tf is added, select required frames like `camera_link` and `l_trail` to see the tfs.

-7. You can also update ros parameter from launch file. Currently, the `pipe_weights.pt` file is the one used. This file can be changed and you can update the parameter name `best_weights` inside the `pipe_detection.launch.py` file.
