-# FastAPI Application
+# NoteTaker API
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A full-featured Note Taking API built with FastAPI and SQLite that allows users to create, manage, and organize their notes.
+
+## Features
+
+- User authentication with JWT
+- Create, read, update, and delete notes
+- Tag notes for better organization
+- Archive and pin notes
+- Search functionality for notes
+- RESTful API with Swagger documentation
+
+## Tech Stack
+
+- **Backend Framework**: FastAPI
+- **Database**: SQLite with SQLAlchemy ORM
+- **Authentication**: JWT (JSON Web Tokens)
+- **Migration Tool**: Alembic
+- **Documentation**: Swagger UI, ReDoc
+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.8+
+- pip
+
+### Installation
+
+1. Clone the repository:
+   ```bash
+   git clone <repository-url>
+   cd notetaker-api
+   ```
+
+2. Install dependencies:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+3. Run database migrations:
+   ```bash
+   alembic upgrade head
+   ```
+
+4. Run the development server:
+   ```bash
+   uvicorn main:app --reload
+   ```
+
+The API will be available at `http://localhost:8000`
+
+### Environment Variables
+
+Set the following environment variables for production:
+
+- `SECRET_KEY`: A secret key for JWT token generation
+- `ALGORITHM`: The algorithm used for JWT encoding (default: "HS256")
+- `ACCESS_TOKEN_EXPIRE_MINUTES`: Minutes until a token expires (default: 10080 - 7 days)
+
+## API Documentation
+
+The API documentation is available at:
+
+- Swagger UI: `http://localhost:8000/docs`
+- ReDoc: `http://localhost:8000/redoc`
+
+## Database Schema
