+## Troubleshooting
+If you think this mod is causing issues, follow these steps:
+1. Open Content Manager and go to the **Mods Panel**, disable all except "Network Extensions 2".
+2. In Content Manager, go to the **Asset Panel** and disable all except the assets listed in the "Required Assets List".
+3. Quit to Desktop.
+4. Verify game cache.
+5. Launch the game and start a new game 100% vanilla (DLC allowed, but no other mods).
+6. Test the mod thoroughly.
+7. If the problem persists, please document your findings and upload a vanilla save file for testing.
+
+## Links & Credits
+- **Multiplayer**: Compatible with [Cities: Skylines Multiplayer (CSM)](https://github.com/CSM-Developers/CSM).
+- **Original Mod**: Credits to the original Team NeXT for the foundation.
