git remote add upstream https://github.com/tinkle-community/nofx.git
```

### 2. Create a Feature Branch

```bash
# Update your local dev branch
git checkout dev
git pull upstream dev

# Create a new branch
git checkout -b feature/your-feature-name
# or
git checkout -b fix/your-bug-fix
```

**Branch Naming Convention:**
- `feature/` - New features
- `fix/` - Bug fixes
- `docs/` - Documentation updates
- `refactor/` - Code refactoring
- `perf/` - Performance improvements
- `test/` - Test updates

- [ ] No linting errors (`go fmt`, `go vet`)
- [ ] Documentation is updated
- [ ] Commits follow conventional commits format
- [ ] Branch is rebased on latest `dev`

### PR Title Format

Use [Conventional Commits](https://www.conventionalcommits.org/) format:

```
<type>(<scope>): <subject>

Examples:
feat(exchange): add OKX exchange integration
fix(trader): resolve position tracking bug
docs(readme): update installation instructions
perf(ai): optimize prompt generation
refactor(core): extract common exchange interface
```

**Types:**
- `feat` - New feature
- `fix` - Bug fix
- `docs` - Documentation
- `style` - Code style (formatting, no logic change)
- `refactor` - Code refactoring
- `perf` - Performance improvement
- `test` - Test updates
- `chore` - Build/config changes

2. **Type of change** is marked
3. **Related issues** are linked
4. **Testing steps** are documented
5. **Screenshots** for UI changes
6. **All checkboxes** are completed

### PR Size

Keep PRs focused and reasonably sized:

- ✅ **Small PR** (< 300 lines): Ideal, fast review
- ⚠️ **Medium PR** (300-1000 lines): Acceptable, may take longer
- ❌ **Large PR** (> 1000 lines): Please break into smaller PRs

## 💻 Coding Standards

### Go Code

```go
// ✅ Good: Clear naming, proper error handling
func ConnectToExchange(apiKey, secret string) (*Exchange, error) {
    if apiKey == "" || secret == "" {
        return nil, fmt.Errorf("API credentials are required")
    }

    client, err := createClient(apiKey, secret)
    if err != nil {
        return nil, fmt.Errorf("failed to create client: %w", err)
    }

    return &Exchange{client: client}, nil
}

// ❌ Bad: Poor naming, no error handling
func ce(a, s string) *Exchange {
    c := createClient(a, s)
    return &Exchange{client: c}
}
```

**Best Practices:**
- Use meaningful variable names
- Handle all errors explicitly
- Add comments for complex logic
- Follow Go idioms and conventions
- Run `go fmt` before committing
- Use `go vet` and `golangci-lint`

### TypeScript/React Code

```typescript
// ✅ Good: Type-safe, clear naming
interface TraderConfig {
  id: string;
  exchange: 'binance' | 'hyperliquid' | 'aster';
  aiModel: string;
  enabled: boolean;
}

const TraderCard: React.FC<{ trader: TraderConfig }> = ({ trader }) => {
  const [isRunning, setIsRunning] = useState(false);

  const handleStart = async () => {
    try {
      await startTrader(trader.id);
      setIsRunning(true);
    } catch (error) {
      console.error('Failed to start trader:', error);
    }
  };

  return <div>...</div>;
};

// ❌ Bad: No types, unclear naming
const TC = (props) => {
  const [r, setR] = useState(false);
  const h = () => { startTrader(props.t.id); setR(true); };
  return <div>...</div>;
};
```

**Best Practices:**
- Use TypeScript strict mode
- Define interfaces for all data structures
- Avoid `any` type
- Use functional components with hooks
- Follow React best practices
- Run `npm run lint` before committing
