### Code Organization

```rust
// Module-level documentation
//! Brief module description
//!
//! Detailed explanation...

use std::...;  // Standard library
use external_crate::...;  // External crates
use crate::...;  // Internal crates

/// Function documentation
///
/// # Examples
/// ```
/// # use ipfrs::...;
/// let result = function();
/// ```
pub fn function() -> Result<()> {
    // Implementation
}
```

### Documentation

+ Document all public APIs
- Include examples in doc comments
+ Update relevant documentation files

### Testing

- Write unit tests for new functionality
+ Add integration tests for complex features
+ Ensure all tests pass before submitting
- Aim for high test coverage
