+# Agent Guidelines for Leggen
+
+## Quick Setup for Development
+
+### Prerequisites
+- **uv** must be installed for Python dependency management (can be installed via `pip install uv`)
+- **Configuration file**: Copy `config.example.toml` to `config.toml` before running any commands:
+  ```bash
+  cp config.example.toml config.toml
+  ```
+
+### Generate Mock Database
+The leggen CLI provides a command to generate a mock database for testing:
+
+```bash
+# Generate sample database with default settings (3 accounts, 50 transactions each)
+uv run leggen --config config.toml generate_sample_db --database /path/to/test.db --force
+
+# Custom configuration
+uv run leggen --config config.toml generate_sample_db --database ./test-data.db --accounts 5 --transactions 100 --force
+```
+
+The command outputs instructions for setting the required environment variable to use the generated database.
+
+### Start the API Server
+1. Install uv if not already installed: `pip install uv`
+2. Set the database environment variable to point to your generated mock database:
+   ```bash
+   export LEGGEN_DATABASE_PATH=/path/to/your/generated/database.db
+   ```
+3. Ensure the API can find the configuration file (choose one):
+   ```bash
+   # Option 1: Copy config to the expected location
+   mkdir -p ~/.config/leggen && cp config.toml ~/.config/leggen/config.toml
+   
+   # Option 2: Set environment variable to current config file
+   export LEGGEN_CONFIG_FILE=./config.toml
+   ```
+4. Start the API server:
+   ```bash
+   uv run leggen server
+   ```
+   - For development mode with auto-reload: `uv run leggen server --reload`
+   - API will be available at `http://localhost:8000` with docs at `http://localhost:8000/docs`
+
+### Start the Frontend
+1. Navigate to the frontend directory: `cd frontend`
+2. Install npm dependencies: `npm install`
+3. Start the development server: `npm run dev`
+   - Frontend will be available at `http://localhost:3000`
+   - The frontend is configured to connect to the API at `http://localhost:8000/api/v1`
+
+## Build/Lint/Test Commands
+
+### Frontend (React/TypeScript)
+- **Dev server**: `cd frontend && npm run dev`
+- **Build**: `cd frontend && npm run build`
+- **Lint**: `cd frontend && npm run lint`
+
+### Backend (Python)
+- **Lint**: `uv run ruff check .`
+- **Format**: `uv run ruff format .`
+- **Type check**: `uv run mypy leggen --check-untyped-defs`
+- **All checks**: `uv run pre-commit run --all-files`
+- **Run all tests**: `uv run pytest`
+- **Run single test**: `uv run pytest tests/unit/test_api_accounts.py::TestAccountsAPI::test_get_all_accounts_success -v`
+- **Run tests by marker**: `uv run pytest -m "api"` or `uv run pytest -m "unit"`
+
+## Code Style Guidelines
+
+### Python
+- **Imports**: Standard library → Third-party → Local (blank lines between groups)
+- **Naming**: snake_case for variables/functions, PascalCase for classes
+- **Types**: Use type hints for all function parameters and return values
+- **Error handling**: Use specific exceptions, loguru for logging
+- **Path handling**: Use `pathlib.Path` instead of `os.path`
+- **CLI**: Use Click framework with proper option decorators
+
+### TypeScript/React
+- **Imports**: React hooks first, then third-party, then local components/types
+- **Naming**: PascalCase for components, camelCase for variables/functions
+- **Types**: Use `import type` for type-only imports, define interfaces/types
+- **Styling**: Tailwind CSS with `clsx` utility for conditional classes
+- **Icons**: lucide-react with consistent naming
+- **Data fetching**: @tanstack/react-query with proper error handling
+- **Components**: Functional components with hooks, proper TypeScript typing
+
+### General
+- **Formatting**: ruff for Python, ESLint for TypeScript
+- **Commits**: Use conventional commits with optional scopes, run pre-commit hooks before pushing
+  - Format: `type(scope): Description starting with uppercase and ending with period.`
+  - Scopes: `cli`, `api`, `frontend` (optional)
+  - Types: `feat`, `fix`, `refactor` (avoid too many different types)
+  - Examples:
+    - `feat(frontend): Add support for S3 backups.`
+    - `fix(api): Resolve authentication timeout issues.`
+    - `refactor(cli): Improve error handling for missing config.`
+  - Avoid including specific numbers, counts, or data-dependent information that may become outdated
+- **Security**: Never log sensitive data, use environment variables for secrets
+
+## Contributing Guidelines
+
+This repository follows conventional changelog practices. Refer to `CONTRIBUTING.md` for detailed contribution guidelines including:
+- Commit message format and scoping
+- Release process using `scripts/release.sh`
+- Pre-commit hooks setup with `pre-commit install`

-An Open Banking CLI.
+An Open Banking CLI and API service for managing bank connections and transactions.
 
-This tool aims to provide a simple way to connect to banks using the GoCardless Open Banking API.
+This tool provides a **unified command-line interface** (`leggen`) with both CLI commands and an integrated **FastAPI backend service**, plus a **React Web Interface** to connect to banks using the GoCardless Open Banking API.
 
-Having a simple CLI tool to connect to banks and list transactions can be very useful for developers and companies that need to access bank data.
-
-Having your bank data in a database, gives you the power to backup, analyze and create reports with your data.
+Having your bank data accessible through both CLI and REST API gives you the power to backup, analyze, create reports, and integrate with other applications.
 
 ## 🛠️ Technologies
-  - Python: for the CLI
+
+  ### 🔌 API & Backend
+  - [FastAPI](https://fastapi.tiangolo.com/): High-performance async API backend (integrated into `leggen server`)
   - [GoCardless Open Banking API](https://developer.gocardless.com/bank-account-data/overview): for connecting to banks
+  - [APScheduler](https://apscheduler.readthedocs.io/): Background job scheduling with configurable cron
+
+  ### 📦 Storage
   - [SQLite](https://www.sqlite.org): for storing transactions, simple and easy to use
-  - [NocoDB](https://github.com/nocodb/nocodb): for visualizing and querying transactions, a simple and easy to use interface for SQLite
-  - [Ofelia](https://github.com/mcuadros/ofelia): for scheduling regular syncs with the database when using Docker
-  - [MongoDB](https://www.mongodb.com/docs/): alternative store for transactions, good balance between performance and query capabilities
+
+  ### Frontend
+  - [React](https://reactjs.org/): Modern web interface with TypeScript
+  - [Vite](https://vitejs.dev/): Fast build tool and development server
+  - [Tailwind CSS](https://tailwindcss.com/): Utility-first CSS framework
+  - [TanStack Query](https://tanstack.com/query): Powerful data synchronization for React
 
 ## ✨ Features
-  - Connect to banks using GoCardless Open Banking API
-  - List all connected banks and their status
-  - List balances of all connected accounts
-  - List transactions for all connected accounts
-  - Sync all transactions with a MongoDB database
 
-## 🚀 Installation and Configuration
+### 🎯 Core Banking Features
+- Connect to banks using GoCardless Open Banking API (30+ EU countries)
+- List all connected banks and their connection statuses
+- View balances of all connected accounts
+- List and filter transactions across all accounts
+- Support for both booked and pending transactions
 
-In order to use `leggen`, you need to create a GoCardless account. GoCardless is a service that provides access to Open Banking APIs. You can create an account at https://gocardless.com/bank-account-data/.
+### 🔄 Data Management
+- Sync all transactions with SQLite database
+- Background sync scheduling with configurable cron expressions
+- Automatic transaction deduplication and status tracking
+- Real-time sync status monitoring
 
-After creating an account and getting your API keys, the best way is to use the [compose file](docker-compose.yml). Open the file and adapt it to your needs. Then run the following command:
+### 📡 API & Integration
+- **REST API**: Complete FastAPI backend with comprehensive endpoints
+- **CLI Interface**: Enhanced command-line tools with new options
+
+### 🔔 Notifications & Monitoring
+- Discord and Telegram notifications for filtered transactions
+- Configurable transaction filters (case-sensitive/insensitive)
+- Account expiry notifications and status alerts
+- Comprehensive logging and error handling
+
+## 🚀 Quick Start
+
+### Prerequisites
+1. Create a GoCardless account at [https://gocardless.com/bank-account-data/](https://gocardless.com/bank-account-data/)
+2. Get your API credentials (key and secret)
+
+### Installation Options
+
+#### Option 1: Docker Compose (Recommended)
+The easiest way to get started is with Docker Compose, which includes both the React frontend and FastAPI backend:
 
 ```bash
-$ docker compose up -d
+# Clone the repository
+git clone https://github.com/elisiariocouto/leggen.git
+cd leggen
+
+# Create your configuration
+mkdir -p data && cp config.example.toml data/config.toml
+# Edit data/config.toml with your GoCardless credentials
+
+# Start all services (frontend + backend)
+docker compose up -d
+
+# Access the web interface at http://localhost:3000
+# API is available at http://localhost:8000
 ```
 
-The leggen container will exit, this is expected. Now you can run the following command to create the configuration file:
+#### Production Deployment
+
+For production deployment using published Docker images:
 
 ```bash
-$ docker compose run leggen init
+# Clone the repository
+git clone https://github.com/elisiariocouto/leggen.git
+cd leggen
+
+# Create your configuration
+mkdir -p data && cp config.example.toml data/config.toml
+# Edit data/config.toml with your GoCardless credentials
+
+# Start production services
+docker compose up -d
+
+# Access the web interface at http://localhost:3000
+# API is available at http://localhost:8000
 ```
 
-Now you need to connect your bank accounts. Run the following command and follow the instructions:
+### Development vs Production
+
+- **Development**: Use `docker compose -f compose.dev.yml up -d` (builds from source)
+- **Production**: Use `docker compose up -d` (uses published images)
+
+#### Option 2: Local Development
+For development or local installation:
 
 ```bash
-$ docker compose run leggen bank add
+# Install with uv (recommended) or pip
+uv sync  # or pip install -e .
+
+# Start the API service
+uv run leggen server --reload  # Development mode with auto-reload
+
+# Use the CLI (in another terminal)
+uv run leggen --help
 ```
 
-To sync all transactions with the database, run the following command:
+### Configuration
+
+Create a configuration file at `./data/config.toml` (for Docker) or `~/.config/leggen/config.toml` (for local development):
+
+```toml
+[gocardless]
+key = "your-api-key"
+secret = "your-secret-key"
+url = "https://bankaccountdata.gocardless.com/api/v2"
+
+[database]
+sqlite = true
+
+# Optional: Background sync scheduling
+[scheduler.sync]
+enabled = true
+hour = 3      # 3 AM
+minute = 0
+# cron = "0 3 * * *"  # Alternative: use cron expression
+
+# Optional: Discord notifications
+[notifications.discord]
+webhook = "https://discord.com/api/webhooks/..."
+enabled = true
+
+# Optional: Telegram notifications
+[notifications.telegram]
+token = "your-bot-token"
+chat_id = 12345
+enabled = true
+
+# Optional: Transaction filters for notifications
+[filters]
+case-insensitive = ["salary", "utility"]
+case-sensitive = ["SpecificStore"]
+```
+

+# Leggen Frontend
+
+A modern React dashboard for the Leggen Open Banking CLI tool. This frontend provides a user-friendly interface to view bank accounts, transactions, and balances.
+
+## Features
+
+- **Modern Dashboard**: Clean, responsive interface built with React and TypeScript
+- **Bank Accounts Overview**: View all connected bank accounts with real-time balances
+- **Transaction Management**: Browse, search, and filter transactions across all accounts
+- **Responsive Design**: Works seamlessly on desktop, tablet, and mobile devices
+- **Real-time Data**: Powered by React Query for efficient data fetching and caching
+
+## Prerequisites
+
+- Node.js 18+ and npm
+- Leggen API server running (configurable via environment variables)
+
+## Getting Started
+
+1. **Install dependencies:**
+
+   ```bash
+   npm install
+   ```
+
+2. **Start the development server:**
+
+   ```bash
+   npm run dev
+   ```
+
+3. **Open your browser to:**
+   ```
+   http://localhost:5173
+   ```
+
+## Available Scripts
+
+- `npm run dev` - Start development server
+- `npm run build` - Build for production
+- `npm run preview` - Preview production build
+- `npm run lint` - Run ESLint
+
+## Architecture
+
+### Key Technologies
+
+- **React 18** - Modern React with hooks and concurrent features
+- **TypeScript** - Type-safe JavaScript development
+- **Vite** - Fast build tool and development server
+- **Tailwind CSS** - Utility-first CSS framework
+- **React Query** - Data fetching and caching
+- **Axios** - HTTP client for API calls
+- **Lucide React** - Modern icon library
+
+### Project Structure
+
+```
+src/
+├── components/          # React components
+│   ├── Dashboard.tsx    # Main dashboard layout
+│   ├── AccountsOverview.tsx
+│   └── TransactionsList.tsx
+├── lib/                # Utilities and API client
+│   ├── api.ts          # API client and endpoints
+│   └── utils.ts        # Helper functions
+├── types/              # TypeScript type definitions
+│   └── api.ts          # API response types
+└── App.tsx             # Main application component
+```
+
+## API Integration
+
+The frontend connects to the Leggen API server (configurable via environment variables). The API client handles:
+
+- Account retrieval and management
+- Transaction fetching with filtering
+- Balance information
+- Error handling and loading states
+
+## Configuration
+
+### API URL Configuration
+
+The frontend supports configurable API URLs through environment variables:
+
+**Development:**
+
+- Set `VITE_API_URL` to call external APIs during development
+- Example: `VITE_API_URL=https://staging-api.example.com npm run dev`
+
+**Production:**
+
+- Uses relative URLs (`/api/v1`) that nginx proxies to the backend
+- Configure nginx proxy target via `API_BACKEND_URL` environment variable
+- Default: `http://leggen-server:8000`
+
+**Docker Compose:**
+
+```bash
+# Override API backend URL
+API_BACKEND_URL=https://prod-api.example.com docker-compose up
+```
+
+## Development
+
+The dashboard is designed to work with the Leggen CLI tool's API endpoints. Make sure your Leggen server is running before starting the frontend development server.
+
+### Adding New Features
+
+1. Define TypeScript types in `src/types/api.ts`
+2. Add API methods to `src/lib/api.ts`
+3. Create React components in `src/components/`
+4. Use React Query for data fetching and state management
+
+## Deployment
+
+Build the application for production:
+
+```bash
+npm run build
+```
+
+The built files will be in the `dist/` directory, ready to be served by any static web server.
