## 🚀 Quick Start (3 Commands)

### 1. Start Server
```bash
cd E:\rr3\RR3CommunityServer\RR3CommunityServer
dotnet run
```

**Expected Output:**
```
╔══════════════════════════════════════════════════════════╗
║      Real Racing 3 Community Server - RUNNING          ║
╠══════════════════════════════════════════════════════════╣
║  Server is ready to accept connections                 ║
║  Ensure DNS/hosts file points EA servers to this IP    ║
╚══════════════════════════════════════════════════════════╝

Listening on: https://localhost:5001
Director endpoint: /director/api/android/getDirectionByPackage
```

### 2. Test Connection
**Open browser:** `https://localhost:5001/swagger`

Or test with curl:
```bash
curl -k https://localhost:5001/director/api/android/getDirectionByPackage?packageName=com.ea.games.r3_row
```

**Expected Response:**
```json
{
  "resultCode": 0,
  "message": "Success",
  "data": {
    "serverUrls": {
      "synergy.product": "https://localhost:5001",
