## Requirements & limits

- Install pefile with Python 3; the module is self-contained and documents Windows, macOS and Linux operation. Understanding the PE layout is needed to interpret its structures.
- Its editing helpers do not rearrange PE structures to make room for new fields. Signature verification is referred to a separate project.
