## Overview

This repository builds and distributes Windows Vim snapshots, rather than implementing the Vim editor itself. The documented workflow is automated builds, optional patch application, packaging as installers and architecture-specific archives, then release distribution; nightly builds also go to WinGet. README capabilities include signed builds and optional interpreter and terminal/encryption support in the binaries. Workflow and packaging source was not sampled, so links are limited to relationships documented in the README or evident in the launcher source.

Main entry points: [`package`](https://github.com/vim/vim-win32-installer/tree/master/package) (Package contents), [`.github/workflows`](https://github.com/vim/vim-win32-installer/tree/master/.github/workflows) (Build automation), [`nsis/gvim.nsi`](https://github.com/vim/vim-win32-installer/blob/master/nsis/gvim.nsi) (NSIS installer), [`vim-launcher/vim-launcher.c`](https://github.com/vim/vim-win32-installer/blob/master/vim-launcher/vim-launcher.c) (Vim launcher)
