 A small and simple Tool to send UDP packages over custom ports to control logic in Unity projects.
 
+## Storage
+
+All projects and packages are stored in a **JSON file** located in your Documents folder:
+- **Windows**: `C:\Users\<YourUsername>\Documents\unityudp_projects.json`
+- **macOS**: `~/Documents/unityudp_projects.json`
+- **Linux**: `~/Documents/unityudp_projects.json`
+
+This makes it easy to:
+- 📤 **Share** projects with other users
+- 💾 **Backup** your configurations
+- 📝 **Edit** manually if needed (JSON format)
+- 🔄 **Version control** with Git
+
+Click the folder icon in the app to see the exact file location on your system.
