-# FastAPI Application
+# Rental Services API
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+This is a FastAPI application for managing rental services. It provides endpoints for managing rental items, categories, customers, and rental records.
+
+## Features
+
+- Rental items management (with categories)
+- Customer management
+- Rental records tracking
+- SQLite database with SQLAlchemy ORM
+- Alembic for database migrations
+- OpenAPI documentation
+
+## API Endpoints
+
+### Health Check
+- GET `/health` - Check API health
+
+### Categories
+- GET `/api/v1/rentals/categories/` - List all categories
+- GET `/api/v1/rentals/categories/{category_id}` - Get category by ID
+
+### Rental Items
+- GET `/api/v1/rentals/items/` - List all rental items
+  - Query params: 
+    - `category_id` - Filter by category
+    - `available_only` - Filter by availability
+- GET `/api/v1/rentals/items/{item_id}` - Get rental item by ID
+
+### Customers
+- GET `/api/v1/rentals/customers/` - List all customers
+- GET `/api/v1/rentals/customers/{customer_id}` - Get customer by ID
+- GET `/api/v1/rentals/customers/email/{email}` - Get customer by email
+
+### Rental Records
+- GET `/api/v1/rentals/records/` - List all rental records
+  - Query params:
+    - `customer_id` - Filter by customer
+    - `item_id` - Filter by rental item
+    - `active_only` - Filter active rentals only
+- GET `/api/v1/rentals/records/{record_id}` - Get rental record by ID

+
+## Setup and Running
+
+1. Install dependencies:
+   ```
+   pip install -r requirements.txt
+   ```
+
+2. Run database migrations:
+   ```
+   alembic upgrade head
+   ```
+
+3. Start the API server:
+   ```
+   uvicorn main:app --reload
+   ```
+
+4. Access the API documentation:
+   - Swagger UI: http://localhost:8000/docs
+   - ReDoc: http://localhost:8000/redoc
+
+## Environment Variables
+
+The application uses environment variables for configuration. Create a `.env` file in the root directory with the following variables:
+
+```
+PROJECT_NAME=Rental Services API
+API_V1_STR=/api/v1
+```
+
+## Database
+
+The application uses SQLite as the database. The database file is stored at `/app/storage/db/db.sqlite`. Make sure the directory exists or is created at runtime.
