 # DLB Gate Keeper
 
-A Raspberry Pi-based gate control system with a web interface.
+A modern web application for controlling the DLB gate, featuring a beautiful macOS-inspired UI and robust backend.
 
-## Architecture
+## Features
 
-- Backend: Python FastAPI server with direct GPIO control
-- Frontend: React/TypeScript web interface
-- Database: SQLite for event logging and settings
-- Service: Systemd service for automatic startup and monitoring
+- Single-button gate control with automatic state detection
+- Real-time gate status monitoring
+- Event logging for all gate operations
+- Configurable settings for gate timing
+- Mobile-responsive design with glass morphism effects
+- Modern macOS-inspired user interface
 
-## Development Setup
+## Technical Stack
 
-### Backend (Python)
+### Frontend
+- React with TypeScript
+- Tailwind CSS for styling
+- Modern glass morphism design
+- Mobile-first responsive layout
 
-1. Install Python dependencies:
-```bash
-cd backend
-pip install -r requirements.txt
-```
+### Backend
+- FastAPI (Python)
+- SQLite for data persistence
+- RPi.GPIO for hardware control
+- Async operations for improved performance
 
-2. Run the development server:
-```bash
-uvicorn main:app --reload --host 0.0.0.0 --port 3000
-```
+## API Documentation
 
-### Frontend (React)
+### Endpoints
 
-1. Install Node.js dependencies:
-```bash
-cd frontend
-npm install
-```
+#### Gate Control
+- `POST /api/trigger`
+  - Toggles the gate state (open/close)
+  - Response: `{ "success": boolean, "currentStatus": boolean }`
 
-2. Start the development server:
-```bash
-npm run dev
-```
+#### Gate Status
+- `GET /api/status`
+  - Returns current gate status
+  - Response: `{ "isOpen": boolean, "lastChanged": string }`
+
+#### Event History
+- `GET /api/events`
+  - Returns gate operation history
+  - Query Parameters:
+    - `limit`: number (default: 10)
+  - Response: Array of `{ "id": number, "timestamp": string, "action": string, "source": string, "success": boolean }`
+
+#### Settings
+- `GET /api/settings`
+  - Returns current settings
+  - Response: `{ "maxOpenTimeSeconds": string, "triggerDuration": string }`
+- `POST /api/settings`
+  - Updates gate settings
+  - Body: `{ "maxOpenTimeSeconds": string, "triggerDuration": string }`
+  - Response: `{ "success": boolean }`
+
+## Installation
+
+1. Clone the repository:
+   ```bash
+   git clone https://git.athenanetworks.com.au/josh/dlbGatekeeper.git
+   ```
+
+2. Install backend dependencies:
+   ```bash
+   cd backend
+   pip install -r requirements.txt
+   ```
+
+3. Install frontend dependencies:
+   ```bash
+   cd frontend
+   npm install
+   ```
+
+## Development
+
+1. Start the backend:
+   ```bash
+   cd backend
+   python main.py
+   ```
+
+2. Start the frontend development server:
+   ```bash
+   cd frontend
+   npm run dev
+   ```
 
 ## Deployment
 
-1. Deploy to Raspberry Pi:
+Use the deployment script:
 ```bash
 ./deploy.sh
 ```
 
 This will:
-- Build the frontend
-- Package the Python backend
-- Copy files to the Raspberry Pi
-- Install Python dependencies
-- Set up and start the systemd service
+1. Build the frontend
+2. Package all files
+3. Deploy to the Raspberry Pi
+4. Restart the service
 
-## GPIO Setup
+## Configuration
 
-The application uses GPIO pin 17 (BCM numbering) by default. You can change this by setting the `RELAY_PIN` environment variable in the systemd service file.
+### GPIO Pins
+- `RELAY_1_PIN`: 22 (default)
+- `RELAY_2_PIN`: 5 (default)
+- `STATUS_PIN`: 4 (default)
 
-Make sure the gatekeeper user has access to GPIO:
-```bash
-sudo usermod -a -G gpio gatekeeper
-```
+### Timing Settings
+- `maxOpenTimeSeconds`: Maximum time the gate stays open (default: 300 seconds)
+- `triggerDuration`: Duration of the trigger pulse in milliseconds (default: 500ms)
 
-## API Endpoints
+## Status Indicators
 
-- `POST /api/trigger/{direction}` - Trigger gate (direction: "open" or "close")
-- `GET /api/events` - Get recent gate events
-- `GET /api/settings` - Get current settings
-- `POST /api/settings` - Update settings
+- Gate Open: Status LED shows HIGH (3.3V)
+- Gate Closed: Status LED shows LOW (0V)
+
+## Security
+
+- No authentication required (internal network only)
+- CORS enabled for development
+- Rate limiting on API endpoints
