 ## 🚀 How to Run
 
 Clone the repo and open it in [Xcode](https://developer.apple.com/xcode/). You can build and run the app on macOS 14+.
-                                      
+                                     
 ```
 git clone https://git.24unix.net/tracer/iKeyMon
 cd iKeyMon
 open iKeyMon.xcodeproj
 ```
+
+### Local release build
+
+Use the helper script to produce a zipped `.app` in `dist/`:
+
+```bash
+./scripts/build_release.sh
+```
+
+It cleans previous artifacts, builds the `Release` configuration, and drops `iKeyMon-<version>.zip` into the `dist` folder (ignored by git).
