### **Steps to Upgrade**

This guide will walk you through the process of upgrading v2.3 of the ARwayKit SDK to v2.3.1. Please follow the instructions carefully to ensure a smooth transition to the new version.

1. **Download the New Version**: Download the ARway Unity Package v2.3.1 from the official ARway website or your client portal.
2. **Backup Your Project**: Save your Unity project with your version control system (such as Git) to ensure you can revert in case of any unforeseen issues.
3. **Replace ARWayKit.dll**: The only file that has changed between v2.3 and v2.3.1 is located at `/Assets/ARwayKitSDK/Plugins/ARWayKit.dll`. Extract the zip file (or download the file directly from the repo) containing the new version and replace the existing `ARWayKit.dll` in your project with the one from the new package.
4. **Verify Integration**: Double-check that the `ARWayKit.dll` integration went smoothly and there were no errors during import.
5. **Build and Test**: Rebuild your Unity project and thoroughly test all the ARway features and functionalities that your application uses.
