+# scanengine-3
+
+A unified scanning and instrumentation control platform combining multiple hardware control modules.
+
+## Overview
+
+scanengine-3 merges four previously separate projects into a single, cohesive platform:
+
+- **nuescan**: SRAS scan planning and control software with PyQt6 GUI
+- **pymso**: Tektronix oscilloscope control and data acquisition
+- **pybbd202**: Thorlabs BBD203/MLS203 motor controller driver
+- **pypewpewhops**: Coherent HOPS laser control via I2C
+
+## Project Structure
+
+```
+scanengine-3/
+├── nuescan/          # Main scan control application with GUI
+├── pymso/            # Oscilloscope control module
+├── pybbd202/         # Stage controller driver
+├── pypewpewhops/     # Laser control module
+├── requirements.txt  # Unified dependencies
+└── README.md         # This file
+```
+
+## Installation
+
+1. Create a virtual environment:
+   ```bash
+   python -m venv venv
+   source venv/bin/activate  # On Windows: venv\Scripts\activate
+   ```
+
+2. Install dependencies:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+## Dependencies
+
+- **PyQt6**: GUI framework for nuescan
+- **pyserial**: Serial communication for hardware interfaces
+- **pyvisa/pyvisa-py**: VISA instrument control for oscilloscopes
+- **pyftdi**: FTDI device support for laser and stage controllers
+
+## Usage
+
+Refer to the README files in each subdirectory for specific usage instructions:
+
+- `nuescan/README.md` - Main application usage
+- `pymso/` - Oscilloscope control examples
+- `pybbd202/README.md` - Stage controller documentation
+- `pypewpewhops/README.md` - Laser control documentation
