+# Rally Racer
+
+This repository holds a sandbox driving simulation controllable via a network interface as a machine learning and data collection challenge.
+
+# Installation
+From the root of the repository, run
+```sh
+uv sync
+```
+
+To run the game, you can use
+```sh
+uv run main.py
+```
+
+# Generality
+Launching [`main.py`](main.py) starts a race with a single car on the provided track. 
+This track can be controlled either by keyboard (*WASD*) or by a socket interface. 
+An example of such interface is included in the code in [*`scripts/recorder.py`*](scripts/recorder.py). To run it, simply use the following command:
+```sh
+uv run -m scripts.recorder
+```
+
+# Sensing
+The car sensing is available in two commodities: **raycasts** and **images**. These sensing snapshots are sent at 10 Hertz (i.e. 10 times a second). Due to this fact, correct reception of snapshot messages has to be done regularly.
+
+# Communication protocol
+
+A remote controller can be impemented using TCP socket connecting on localhost on port 5000.
+Different commands can be issued to the race simulation to control the car.
+
+These commands are declared in [`src/command.py`](src/command.py)
+
+##  Car controls
+```python
+ControlCommand(control: CarControl, active: bool)
+```
+To simulate key press and control the car.
+
+
+# Controls
+
+- <kbd>W</kbd> Move forward
+- <kbd>S</kbd> Brake / move backward
+- <kbd>A</kbd> Turn left
+- <kbd>D</kbd> Turn right
+- <kbd>F</kbd> Toggle FPS indicator
+- <kbd>V</kbd> Toggle speedometer
+- <kbd>R</kbd> Reset car
+- <kbd>C</kbd> Toggle raycasts visibility
+- <kbd>Esc</kbd> Quit

+# Credits
+This project is based on the repository [https://github.com/ISC-HEI/RallyRobotPilot_2025](https://github.com/ISC-HEI/RallyRobotPilot_2025), which is in turn based on [https://github.com/mandaw2014/Rally](https://github.com/mandaw2014/Rally)
