Notepad3 Documentation

This folder collects the user-facing reference documentation for Notepad3 and its companion file browser MiniPath. The pages here cover end-user topics — configuration, command-line switches, shortcuts, file handling, encryption, theming, and FAQs — and are linked from the main project README and from the in-app Help menu.

Looking for build instructions or contributor notes? See the project README at the repository root and the CLAUDE.md developer guide. For installer / Windows-Notepad-replacement setup, see the project website.
