+
+## 🚀 Quick Deployment
+
+### Option 1: Docker Compose (Recommended)
+```bash
+cd /home/data/finance_bot
+
+# Build and start all services
+docker-compose build
+docker-compose up -d
+
+# Run migrations
+docker-compose exec migrations python -m alembic upgrade head
+
+# Verify
+curl http://localhost:8000/health
+```
+
+**Result:** API running on `http://localhost:8000` with Swagger docs at `/docs`
+
+### Option 2: From Source
+```bash
+cd /home/data/finance_bot
+source .venv/bin/activate
+
+# Start API server
+python -m uvicorn app.main:app --host 0.0.0.0 --port 8000
+
+# In another terminal: Start bot
+python -m app.bot.worker
+```

+## 🔐 Security Features Implemented
+
+### Authentication (Multi-Layer)
+- ✅ **JWT tokens** (15-min access, 30-day refresh)
+- ✅ **HMAC signatures** (prevent tampering & replay attacks)
+- ✅ **Timestamp validation** (±30 seconds tolerance)
+- ✅ **Token expiration** (automatic)
+- ✅ **Service tokens** (for bot)
+- ✅ **Telegram binding** (secure linking flow)
+
+### Authorization (Role-Based)
+- ✅ **5 roles** (Owner, Adult, Member, Child, Read-Only)
+- ✅ **25+ permissions** (granular control)
+- ✅ **Family isolation** (data segregation)
+- ✅ **Resource ownership** (user can only edit own)
+- ✅ **Hierarchy support** (owner can do anything)
+
+### Audit & Compliance
+- ✅ **Event logging** (every action recorded)
+- ✅ **Access logging** (request tracking)
+- ✅ **Immutability** (no deletion, only reversal)
+- ✅ **Compensation transactions** (reversal trail)
+- ✅ **Reason tracking** (why was it changed)
+
+### Infrastructure Security
+- ✅ **Security headers** (HSTS, X-Frame-Options, etc.)
+- ✅ **Rate limiting** (100 req/min per IP)
+- ✅ **CORS control** (whitelist configuration)
+- ✅ **Request validation** (Pydantic models)
+- ✅ **Error handling** (no sensitive info leaks)
+

+
+## 🎯 Example Usage Flows
+
+### User Login & Transaction
+```bash
+# 1. Login
+curl -X POST http://localhost:8000/api/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "user@example.com",
+    "password": "password123"
+  }'
+
+# Response:
+{
+  "access_token": "eyJhbGc...",
+  "refresh_token": "eyJhbGc...",
+  "user_id": 1,
+  "expires_in": 900
+}
+
+# 2. Create transaction
+JWT_TOKEN="eyJhbGc..."
+curl -X POST http://localhost:8000/api/v1/transactions \
+  -H "Authorization: Bearer $JWT_TOKEN" \
+  -H "X-Client-Id: manual_test" \
+  -d '{
+    "family_id": 1,
+    "from_wallet_id": 10,
+    "to_wallet_id": 11,
+    "amount": 50.00,
+    "category_id": 5,
+    "description": "Groceries"
+  }'
+
+# Response:
+{
+  "id": 100,
+  "status": "executed",
+  "amount": "50.00",
+  "confirmation_required": false,
+  "created_at": "2023-12-10T12:30:00Z"
+}
+```
+
+### Telegram Binding
+```bash
+# 1. Bot generates code
+curl -X POST http://localhost:8000/api/v1/auth/telegram/start \
+  -d '{"chat_id": 12345}'
+# Response: {"code": "ABC123XYZ...", "expires_in": 600}
+
+# 2. User clicks binding link
+# https://app.com/auth/telegram?code=ABC123&chat_id=12345
+
+# 3. Confirm binding (as logged-in user)
+curl -X POST http://localhost:8000/api/v1/auth/telegram/confirm \
+  -H "Authorization: Bearer <user_jwt>" \
+  -d '{
+    "code": "ABC123XYZ...",
+    "chat_id": 12345,
+    "username": "john_doe"
+  }'
+# Response: {"success": true, "jwt_token": "...", ...}
+
+# 4. Bot uses JWT for API calls
+# All future bot requests use: Authorization: Bearer <jwt_from_step_3>
+```
