 * This software. It's free and available right here.
 * One of [the 140+ supported cars](docs/CARS.md). We support Honda, Toyota, Hyundai, Nissan, Kia, Chrysler, Lexus, Acura, Audi, VW, and more. If your car is not supported, but has adaptive cruise control and lane keeping assist, it's likely able to run openpilot.
 * A supported device to run this software. This can be a [comma two](https://comma.ai/shop/products/two), [comma three](https://comma.ai/shop/products/three), or if you like to experiment, a [Ubuntu computer with webcams](https://github.com/commaai/openpilot/tree/master/tools/webcam).

-Replay driving data
+Stream CAN messages to your device
 -------------
 
-**Hardware needed**: none
+Replay CAN messages as they were recorded using a [panda jungle](https://comma.ai/shop/products/panda-jungle). The jungle has 6x OBD-C ports for connecting all your comma devices.
 
-`unlogger.py` replays data collected with [dashcam](https://github.com/commaai/openpilot/tree/dashcam) or [openpilot](https://github.com/commaai/openpilot).
+`can_replay.py` is a convenient script for when any CAN data will do.
 
-Unlogger with remote data:
+In order to replay specific route:
+```bash
+MOCK=1 selfdrive/boardd/tests/boardd_old.py
 
+# In another terminal:
+python replay/unlogger.py <route-name> <path-to-data-directory>
 ```
+
+Replay driving data
+-------------
+
+`unlogger.py` replays all the messages logged while running openpilot.
+
+Unlogger with remote data:
+
+```bash
 # Log in via browser
 python lib/auth.py
 
 # Start unlogger
 python replay/unlogger.py <route-name>
-#Example:
-#python replay/unlogger.py '3533c53bb29502d1|2019-12-10--01-13-27'
+# Example:
+# python replay/unlogger.py '3533c53bb29502d1|2019-12-10--01-13-27'
 
 # In another terminal you can run a debug visualizer:
 python replay/ui.py   # Define the environmental variable HORIZONTAL is the ui layout is too tall
-```
-
-Unlogger with local data downloaded from device or https://connect.comma.ai:
 
+# Or run the normal openpilot UI
+cd selffdrive/ui && ./ui
 ```
-python replay/unlogger.py <route-name> <path-to-data-directory>
-
-#Example:
 
-#python replay/unlogger.py '99c94dc769b5d96e|2018-11-14--13-31-42' /home/batman/unlogger_data

-LogReader with remote data
-
-```python
-from tools.lib.logreader import LogReader
-from tools.lib.route import Route
-route = Route('3533c53bb29502d1|2019-12-10--01-13-27')

-events_seg0 = list(LogReader(log_paths[0]))
-print(len(events_seg0), 'events logged in first segment')
-```

-Stream replayed CAN messages to EON
--------------
-
-**Hardware needed**: 2 x [panda](panda.comma.ai), [debug board](https://comma.ai/shop/products/panda-debug-board/), [EON](https://comma.ai/shop/products/eon-gold-dashcam-devkit/).
-
-It is possible to replay CAN messages as they were recorded and forward them to a EON. 
-Connect 2 pandas to the debug board. A panda connects to the PC, the other panda connects to the EON.
-
-Usage:
-```
-# With MOCK=1 boardd will read logged can messages from a replay and send them to the panda.
-MOCK=1 selfdrive/boardd/tests/boardd_old.py
-
-# In another terminal:
-python replay/unlogger.py <route-name> <path-to-data-directory>
-
+## usage
+``` bash
+$ ./unlogger.py -h
