+# OpenCode Desktop
+
+Native OpenCode desktop app, built with Tauri v2.
+
+## Development
+
+From the repo root:
+
+```bash
+bun install
+bun run --cwd packages/desktop tauri dev
+```
+
+This starts the Vite dev server on http://localhost:1420 and opens the native window.
+
+If you only want the web dev server (no native shell):
+
+```bash
+bun run --cwd packages/desktop dev
+```
+
+## Build
+
+To create a production `dist/` and build the native app bundle:
+
+```bash
+bun run --cwd packages/desktop tauri build
+```
+
+## Prerequisites
+
+Running the desktop app requires additional Tauri dependencies (Rust toolchain, platform-specific libraries). See the [Tauri prerequisites](https://v2.tauri.app/start/prerequisites/) for setup instructions.

+# Tauri Icons
+
+Here's the process I've been using to create icons:
+
+- Save source image as `app-icon.png` in `packages/desktop`
+- `cd` to `packages/desktop`
+- Run `bun tauri icon -o src-tauri/icons/{environment}`
+- Use [Image2Icon](https://img2icnsapp.com/)'s 'Big Sur Icon' preset to generate an `icon.icns` file and place it in the appropriate icons folder
+
+The Image2Icon step is necessary as the `icon.icns` generated by `app-icon.png` does not apply the shadow/padding expected by macOS,
+so app icons appear larger than expected.
