-# Kingdom-Cheat-Deliverance-2
+# Kingdom Cheat: Deliverance 2
 
+A game overlay for **Kingdom Come: Deliverance II** with a searchable database of
+console commands, items, perks, buffs and skills. Fill in the parameters, hit
+**Copy**, and paste the finished command into the game console.
+
+- **Overlay**: frameless, semi-transparent, always-on-top window toggled with a
+  global hotkey (default `Ctrl+Shift+K`); lives in the system tray
+- **Quick Cheats**: money, skills & XP, god mode, repair, unlocks, teleport, saving
+- **Commands**: ~120 commands — vanilla `-devmode` commands and the Nexus
+  "Cheat" mod's `cheat_*` commands, each badged by requirement, with argument
+  forms and examples
+- **Items / Perks / Buffs / Skills**: ~4,900 items, ~880 perks, ~560 buffs and all
+  skills with IDs — set amount/condition/level and copy a ready-made command
+
+## Game setup
+
+1. **Borderless window**: set the game's display mode to *borderless window*
+   (an overlay cannot draw above exclusive fullscreen).
+2. **devmode commands** (green badge): add `-devmode` to the game's launch
+   options (Steam → right-click the game → Properties → Launch Options). Open
+   the in-game console with `~` / `` ` ``.
+3. **Cheat mod commands** (purple badge): install the free
+   [Cheat mod](https://www.nexusmods.com/kingdomcomedeliverance2/mods/114)
+   from Nexus Mods (also requires `-devmode`).
+
+## Usage
+
+- Press the global hotkey (default `Ctrl+Shift+K`) or click the tray icon to
+  show/hide the overlay. Closing the window only hides it; quit from the tray menu.
+- Change the hotkey, overlay opacity, preferred command flavor, autostart and
+  start-hidden behavior in **Settings**.
+- **Wayland note**: global hotkeys are unreliable on Wayland. Bind
+  `kcd2-overlay --toggle` to a compositor shortcut instead — a second launch
+  toggles the running instance.
+
+## Building
+
+Prerequisites: Rust, Node.js 20+, and on Linux the Tauri system deps
+(`libwebkit2gtk-4.1-dev libgtk-3-dev libayatana-appindicator3-dev librsvg2-dev`).
+
+```sh
+npm install
+npm run tauri dev     # development
+npm run tauri build   # release bundles (deb/AppImage on Linux, NSIS/MSI on Windows)
+```
+
+Windows builds are produced by the CI workflow in `.github/workflows/build.yml`
+(GitHub Actions / Gitea Actions with a Windows runner), or locally from Linux
+with [cargo-xwin](https://github.com/rust-cross/cargo-xwin):
+`npm run tauri build -- --runner cargo-xwin --target x86_64-pc-windows-msvc`.
+
+## Data
+
+Game data under `src/data/` is generated from the
+[pryans/kcd2-cheat](https://github.com/pryans/kcd2-cheat) repository (the
+source of the Nexus Cheat mod) and vendored so builds are offline:
+
+```sh
+node scripts/fetch-data.mjs   # refresh items/perks/buffs/skills + command docs
+```
+
+`commands-vanilla.json` and `quick-cheats.json` are hand-curated from
+community command lists.
+
+## Disclaimer
+
+Single-player cheats only. Achievements and game balance are your own
+responsibility — keep a save from before you start experimenting.
