## 🚀 Quick Start

### 1. Clone the Project

```bash
git clone https://github.com/linux-do/credit.git
cd credit
```

### 2. Configure Environment

Copy the configuration file and edit it:

```bash
cp config.example.yaml config.yaml
```

Edit `config.yaml` to configure database connections, Redis, OAuth2, etc.

### 3. Initialize Database

```bash
# Create database
createdb -h <host> -p 5432 -U postgres linux_do_credit

# If you need to specify encoding, use:
# psql -h <host> -p 5432 -U postgres -c "CREATE DATABASE linux_do_credit WITH ENCODING 'UTF8' LC_COLLATE='zh_CN.UTF-8' LC_CTYPE='zh_CN.UTF-8' TEMPLATE template0;"

# Run migrations (automatically executed when starting the backend)
```

### 4. Start Backend

```bash
# Install Go dependencies
go mod tidy

# Generate API documentation
make swagger

# Start backend service
go run main.go api
```

### 5. Start Frontend

```bash
cd frontend

# Install dependencies
pnpm install

# Start development server
pnpm dev
```

### 6. Access Application

- **Frontend Interface**: http://localhost:3000
- **API Documentation**: http://localhost:8000/swagger/index.html
- **Health Check**: http://localhost:8000/api/health

```bash
# Run API server
go run main.go api

# Run task scheduler
go run main.go scheduler

# Run worker queue
go run main.go worker

# Generate Swagger documentation
make swagger

# Format and check code
make tidy
```

### Frontend Development

```bash
cd frontend

```

## 📚 API Documentation

API documentation is automatically generated by Swagger and can be accessed after starting the backend service:

```
http://localhost:8000/swagger/index.html
```

## 🧪 Testing

```bash
# Backend testing
go test ./...

# Frontend testing
cd frontend
pnpm test
```

## 🚀 Deployment

### Docker Deployment

```bash
# Build image
docker build -t linux-do-credit .

# Run container
docker run -d -p 8000:8000 linux-do-credit
```

### Production Environment Deployment

1. Build frontend resources:
   ```bash
   cd frontend && pnpm build
   ```

2. Compile backend program:
   ```bash
