# Building from the Source Code
To build the sample app directly from the source code (.zip) provided in the release, follow the below steps.
## **Get the ARwayKit SDK** Source Code
Download the .zip from our [GitHub](https://github.com/arway-ai/unity-viewer-sdk/releases). Please [contact us](https://www.arway.ai/contact) for access.
## Prerequisites
In this guide, we will be using the following versions of Unity:
* **Unity:** 2022.3.62f3
* Include the following platforms in your Unity install:
* Android Build Support
* OpenJDK
* Android SDK & NDK Tools
* iOS Build Support
## **Implementation**
In the instructions below, we will be using the provided .zip source code to create a new app. If you already have an existing Unity app to which you wish to add the package, please refer to the instructions provided in the link below.

### Getting the Account ID and Secret Key
1. From the ARway Creator Portal, go to "For Developers -> Create a New App -> Enter App Name".
2. Copy your **Account ID** and **SecretKey** for that App.
The "For Developers" page of the Creator Portal
### **Opening the Project in Unity**
1. Download the .zip file source code for the latest release.
2. Extract the .zip file to a new folder.
3. Open Unity Hub, and click "Add" > "Add project from disk" and select the extracted zip file.
4. Open the project using Unity Editor Version **2022.3.62f3**.
### **Adding the Account ID and Secret Key**
1. In the Project Window, go to "Assets -> ARway -> Viewer Mode -> Resource-> ARWayKitConfig " and add your credentials for the Account ID and Secret Key.

### **Switch Build Platform to** Android or iOS.
1. "File -> Build Settings -> Build -> Select iOS/Android"
### **Updating the** Addressables Groups
1. Navigate to "Window -> Asset Management -> Addressable -> Groups".
2. In the Addressables Groups window, click on "Build -> New Build -> Default Build Script".

When making any changes that affect localization strings, you will need to update the Addressables Groups.
{% endhint %}
### Android Build Signing
When building for Android, Unity requires a keystore to sign the application.
1. Go to **Project Settings > Player > Android > Publishing Settings**.
2. Under **Custom Keystore**, you have two options:
* **Use your own keystore**: If you have a production key (recommended for release builds), set the path to your `.keystore` file and provide the alias, password, and key details.
* **Use the debug key for testing**: If you don’t need a custom key (e.g., for local development or quick testing), uncheck **Custom Keystore**. Unity will then sign the app automatically with the default debug keystore.
**Important**:
* A debug key is fine for testing, but **Google Play requires your app to be signed with your own keystore**. Make sure to generate and securely store a keystore for release builds.
### Building the App
1. In Unity select "File -> Build Settings".
2. Ensure the following scenes are selected in the following order:
* ARWay/ViewerMode/0\_Scene/Dashboard-SDK
* ARWay/ViewerMode/0\_Scene/ARMapSession
Build Settings Window
3. Change the platform to either Android or iOS by selecting "Android or iOS -> Switch Platform".
4. Select "Build and Run" to run the app.
1. If you see a pop-up for "Unsupported Input Handling" click "Yes"
After successfully building the app on your device, you can scan QR codes that you created for your ARway maps in the Creator Portal.
