-# FastAPI Application
+# Environment Variable Service
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A simple FastAPI application that returns the value of environment variables, specifically designed to return the value of the `NAME` environment variable.
+
+## Features
+
+- Get the value of the `NAME` environment variable
+- Get the value of any environment variable by name
+- Health check endpoint to verify service status
+
+## Installation
+
+1. Clone the repository:
+```bash
+git clone <repository-url>
+cd environmentvariableservice
+```
+
+2. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+
+1. Set environment variables (optional):
+```bash
+export NAME="Your Name"
+```
+
+2. Run the application:
+```bash
+uvicorn main:app --host 0.0.0.0 --port 8000 --reload
+```
+
+3. Access the API:
+   - API documentation: http://localhost:8000/docs
+   - Alternative API documentation: http://localhost:8000/redoc
+   - OpenAPI specification: http://localhost:8000/openapi.json
+
+## API Endpoints
+
+### Get NAME environment variable
+```
+GET /env/name
+```
+Returns the value of the `NAME` environment variable.
+
+### Get any environment variable
+```
+GET /env/{variable_name}
+```
+Returns the value of the specified environment variable.
+
+### Health Check
+```
+GET /health
+```
+Returns the status of the service.
+
+## Development
+
+- The application uses FastAPI for the REST API
+- Environment variables are accessed via the Python `os` module
+- Ruff is used for linting and code formatting
