README

CryDeck

A lightweight Windows desktop shell for [Claude Code](https://claude.com/claude-code). Tabs of Claude sessions, a live file tree, and a preview pane where you can actually use what Claude builds.

Not an IDE. No editor, no LSP, no debugger, no extension host. Claude does the writing; CryDeck is where you watch, steer, and try the result. That omission is the entire reason it stays light (~250MB working set, single small binary).

Getting started (never used a terminal before? start here)

Download CryDeck_x64-setup.exe from the latest release and run it. Windows SmartScreen may warn about an unknown publisher — choose "More info" → "Run anyway".
First launch. CryDeck checks your machine. If Git or Claude Code are missing it offers to install them — click Install and watch it happen in a terminal tab (approve the Windows permission popup if one appears). The tab flows straight into Claude Code's login: you need a Claude account with a Pro or Max plan (https://claude.ai). Already have everything installed? You'll never see any of this.
Make a projects folder. Anywhere you like, e.g. C:\Projects, with one subfolder per project (C:\Projects\my-first-app)
