+# Important ROS Information
+Below you will find information about all the ROS packages, nodes, topics used in this project.
+
+## Packages & Nodes
+Here is a list of packages. Underneath each package are nodes in that package.
+
+------------------------------
+
+### autopilot
+The autopilot node is the brain of the self-driving car. It uses end-to-end
+deep learning to predict the steering, acceleration and braking commands of 
+the vehicle.  while subscribes to the camera feed. (Node currently functioning) The Arduino subsribes to the steering_cmds and controls the steering accordingly.
+
+##### Nodes:
+- `autopilot`
+- `visualization`
+
+##### Publishes
+- `/vehicle/dbw/steering_cmds/`
+- `/vehicle/dbw/cruise_cmds/`
+
+##### Subscribes
+- `/cv_camera_node/image_raw`
+- `/cv_camera_node/image_sim`
+
+------------------------------
+
+### object_detection
+YOLO (You Only Look Once) realtime object detection system.
+
+#### Nodes:
+-  `object_detection_node`
+
+#### Publishes
+- `/detection/object/detection_visualization/`
+- `/detection/object/detection_result`
+
+#### Subscribes:
+- `/cv_camera_node/image_raw`
+
+------------------------------
+
+### segmentation
+Semantic segmentation node. Deep learning, ConvNets
+
+##### Nodes:
+- `segmentation_node`
+
+##### Publishes
+- `/segmentation/visualization/`
+- `/segmentation/output`
+
+##### Subscribes
+- `/cv_camera_node/image_raw`
+
+------------------------------
+
+### cv_camera
+The cameras are the main sensors of the self-driving car. 
+
+##### Nodes:
+- `cv_camera_node`
+
+##### Publishes
+- `/cv_camera_node/image_raw`
+
+------------------------------
+
+### driver
+This is the main package of the project. It pulls together all the individual nodes to create a complete self-driving system.  
+
+##### Nodes:
+- `drive`
+
+------------------------------
+
+### gps
+Used for localization. Currently using the Adafruit GPS module, serial communication.
+
+##### Nodes:
+- `gps_receiver`
+- `nmea_topic_driver`
+- `nmea_topic_serial_reader`
+
+The GPS package manages and publishes the data received from a GPS module connected via serial. The package 
+
+#### Publishes:
+
+- `/sensor/gps/fix`
+- `/sensor/gps/vel`
+
+------------------------------
+
+### data_logger
+The logger node records and compiles a dataset for supervised machine learning purposes. The future is to use rosbag instead of the data_loggar node. (Node currently functioning)
+
+##### Nodes:
+- `logger`
+
+------------------------------
+
+### osm_cartography
+
+#### Nodes:
+- `osm_client`
+- `osm_server`
+- `viz_osm`
+
+This package broadcasts and processes .osm files. OSM files are OpenStreetMap files which contain detailed information about the environment, 
+such as coordinates of roads, building and landmarks. Currently, the main function of the package is to broadcast the osm info to rviz for 
+visualization. (Node currently functioning)
+
+### topics for visualization
+- /visual/steering/angle_img
+- /visual/detection/object/bbox_img
+- /visual/detection/lane/marking_img
+- /visual/segmentation/seg_img
