+# AirbrakesV2
+
+
+## Overview
+This project controls the extension of airbrakes using a servo motor. It includes modules for logging data and managing the servo motor.
+
+### Installation
+Clone the repository:
+
+```
+git clone https://github.com/yourusername/AirbrakesV2.git
+cd AirbrakesV2
+```
+
+#### Set up a virtual environment:
+
+```
+python3 -m venv venv
+source venv/bin/activate
+```
+
+#### Install the required dependencies:
+
+```pip install .[dev]```
+
+#### Install and start the pigpio daemon on the Raspberry Pi:
+
+```bash
+sudo pigpiod
+```
+
+#### Install the mscl library to communicate with the IMU:

+
+### Running Tests
+Our CI pipeline uses [pytest](https://pytest.org) to run tests. You can run the tests locally to ensure that your changes are working as expected.
+
+To run the tests, run this command from the project root directory:
+```pytest```
+
+If you make a change to the code, please make sure to update or add the necessary tests.
+
+### Running the Linter
+
+Our CI also tries to maintain code quality by running a linter. We use [Ruff](https://docs.astral.sh/ruff/).
+
+To run the linter, and fix any issues it finds, run:
+```ruff check . --fix --unsafe-fixes```
+
+To format the code, run:
+```ruff format .```
+
+
+### Usage
+To run the main program, simply run:
+```python3 main.py```
+
+However during development, you may want to run individual scripts to test components. For example, to test the servo, run:
+```python3 -m scripts.run_servo```
