+## 🧹 Package Cleanup & Restore
+
+- **Automatic cleanup on first compile:**  
+  After you configure `config.sh` and run your **first successful build**, the project’s `cleanup.sh` will run to **remove any packages you set to `OFF`**. This reduces dependency bloat to exactly what your project needs.
+
+- **Manual cleanup (optional):**  
+  You can also run cleanup manually at any time from your project directory:  
+  ```bash
+  ./scripts/cleanup.sh
+  ```
+
+- **Restoring removed packages:**  
+  If you later want to **add back packages** you previously turned off (and which `cleanup.sh` removed), run the **template’s** update script from the `cpp-build-system` repository root, pointing it at your project path:  
+  ```bash
+  # from the cpp-build-system repo root
+  ./update_project.sh ~/dev/MyApp
+  ```
+  This will **restore all template-managed packages and scripts** (including `cleanup.sh`) into your project so you can re-enable dependencies via `config.sh` and rebuild.

+## 🧱 Linking Strategy
+
+| Target | Linking Model | Build Environment | Notes |
+|---------|----------------|------------------|-------|
+| **Linux (musl)** | Fully static | Alpine | No shared libs — single binary |
+| **Linux (MinGW64)** | Static as possible | Alpine | Only core Win32 runtime dynamically linked |
+| **Windows (MSYS2)** | Dynamic | MSYS2 | Fallback/test build |
+| **macOS** | Dynamic | Static as possible | Standard Apple toolchain behavior |
+
+> 💡 *Goal: portable, reproducible, single-binary builds across platforms.*
