+## Downloading pre-built binaries
+
+Every push and pull request triggers the [Build and Package](.github/workflows/build.yml) GitHub Actions workflow which compiles the app for Windows, macOS, and Linux.
+
+To download a build:
+1. Go to the [Actions tab](../../actions/workflows/build.yml) of this repository.
+2. Click on any successful workflow run.
+3. Scroll to the **Artifacts** section at the bottom of the run summary.
+4. Download the ZIP for your platform:
+   - `WeAnimate-windows-latest` — contains the Windows folder with `WeAnimate.exe`
+   - `WeAnimate-macos-latest` — contains the macOS `.app` bundle
+   - `WeAnimate-ubuntu-latest` — contains the Linux executable folder
+
+## Building locally
+
+```bash
+# Install dependencies
+npm install
+
+# Build the renderer and Electron main process
+npm run build
+
+# Package for the current platform
+npm run package
+```
+
+Platform-specific packaging scripts are also available:
+
+```bash
+npm run package:win    # Windows (.ico icon)
+npm run package:mac    # macOS (.icns icon)
+npm run package:linux  # Linux (.png icon)
+```
