## Migration Guide

### From v1.x to v2.0

**Before (v1.x)**:
```python
import gorequests

# Manual setup required
setup_gorequests_lib(lib)
make_request = make_request_simple(lib)

# Make request
response = make_request("GET", "https://api.example.com")
```

**After (v2.0)**:
```python
import gorequests

# Zero configuration - just use it!
response = gorequests.get("https://api.example.com")
```

### Breaking Changes
1. **No Manual Setup**: Remove all `setup_gorequests_lib()` calls
2. **Direct Import**: Use `import gorequests` instead of helper functions
3. **Standard API**: Use standard requests-like API (`gorequests.get()`, etc.)
4. **Auto-Configuration**: Library automatically configures itself on first import

### Compatibility
- **Python**: 3.7+ (unchanged)
- **Operating Systems**: Windows, macOS, Linux (unchanged)
- **API**: 100% compatible with Python requests library
- **Performance**: Same or better performance than v1.x
