-# FastAPI Application
+# One-Time Secret Manager API
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+This is a simple API for creating and managing one-time secrets. It allows users to securely share sensitive information by creating secrets that can only be viewed once before being automatically deleted.
+
+## Features
+
+- Create encrypted secrets with customizable expiration time
+- Access secrets using a unique access key
+- Automatic deletion of secrets after they are viewed
+- Secrets expire automatically after the specified time
+- Encrypted storage using strong cryptographic algorithms
+
+## API Endpoints
+
+### Create a New Secret
+
+```
+POST /api/v1/secrets/
+```
+
+**Request Body:**
+```json
+{
+  "content": "Your secret message here",
+  "ttl_hours": 24  // Optional, default is 24 hours, max is 168 hours (7 days)
+}
+```
+
+**Response:**
+```json
+{
+  "access_key": "random_access_key",
+  "expires_at": "2023-09-24T12:00:00.000000",
+  "secret_url": "https://your-domain.com/api/v1/secrets/random_access_key"
+}
+```
+
+### Retrieve a Secret
+
+```
+GET /api/v1/secrets/{access_key}
+```
+
+**Response:**
+```json
+{
+  "content": "Your secret message here",
+  "created_at": "2023-09-23T12:00:00.000000"
+}
+```
+
+### Health Check
+
+```
+GET /health
+```
+
+**Response:**
+```json
+{
+  "status": "healthy"
+}
+```
+
+## Environment Variables
+
+The application uses the following environment variables:
+
+- `SECRET_KEY`: Secret key for encryption (required in production)
+- `ALGORITHM`: JWT algorithm for tokens, default is "HS256"
+- `ACCESS_TOKEN_EXPIRE_MINUTES`: Default token expiration time in minutes, default is 30
+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.8+
+- SQLite
+
+### Installation
+
+1. Clone the repository:
+```bash
+git clone https://github.com/yourusername/onetimesecretmanagerapi.git
+cd onetimesecretmanagerapi
+```
+
+2. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+3. Set up the environment variables:
+```bash
+export SECRET_KEY="your-secret-key"
+```
+
+4. Run database migrations:
+```bash
+alembic upgrade head
+```
+
+5. Start the server:
+```bash
+uvicorn main:app --reload
+```
+
+The API will be available at `http://localhost:8000`.
+
+## Documentation
+
+- API documentation is available at `/docs` when the server is running
+- Redoc documentation is available at `/redoc`
+
+## Security Considerations
+
+- All secrets are encrypted at rest
+- The application uses strong cryptographic algorithms for encryption
+- Secrets are automatically deleted after being viewed once
+- Secrets expire automatically after the specified time
