+## How to Run Object Detection Stack
+
+The object detection stack is a ros2 package. It can be built and ran like any other standard ros2 package. 
+
+Run the following: 
+
+```
+colcon build
+```
+
+```
+source install/setup.bash
+```
+
+```
+ros2 run dist_to_obj_package dist_to_obj_node
+```
+
+## Errors that might occur on launch 
+
+If the ZED camera is not plugged in the following error will pop up: 
+
+```
+Camera Open : CAMERA NOT DETECTED. Exit program.
+```
+
+Sometimes this error will pop up when trying to start object detection: 
+
+```
+NO GPU DETECTED
+```
+
+While it doesn't happen often in the even that it does starting the computer fixes it.
