# Clink (cmd-clink) In-Depth Reference

Comprehensive reference for [clink](https://chrisant996.github.io/clink/) — the tool that injects GNU Readline into Windows `cmd.exe` to provide rich completion, history, and line-editing capabilities. Emphasis on the completion system and how external tools hook into it.
