+# Aircall Server
+
+A standalone server for handling Aircall metrics and data processing.
+
+## Setup
+
+1. Install dependencies:
+```bash
+npm install
+```
+
+2. Set up environment variables:
+```bash
+cp .env.example .env
+```
+Then edit `.env` with your configuration.
+
+Required environment variables:
+- `AIRCALL_API_ID`: Your Aircall API ID
+- `AIRCALL_API_TOKEN`: Your Aircall API Token
+- `MONGODB_URI`: MongoDB connection string
+- `REDIS_URL`: Redis connection string
+- `AIRCALL_PORT`: Server port (default: 3002)
+
+## Running the Server
+
+### Development
+```bash
+npm run dev
+```
+
+### Production
+Using PM2:
+```bash
+pm2 start ecosystem.config.js --env production
+```
+
+## API Endpoints
+
+### GET /api/aircall/metrics/:timeRange
+Get Aircall metrics for a specific time range.
+
+Parameters:
+- `timeRange`: One of ['today', 'yesterday', 'last7days', 'last30days', 'last90days']
+
+### GET /api/aircall/health
+Get server health status.
+
+## Architecture
+
+The server uses:
+- Express.js for the API
+- MongoDB for data storage
+- Redis for caching
+- Winston for logging
