### &#x20;**Enabling APK sideloading on Android devices**

In order to enable your Android device to install APKs downloaded outside of the Play Store, you must first enable the “Install unknown apps” setting on your device. Follow these steps to enable this setting:

1. On your Android device go to **Settings > Apps**
2. Go to **General > Special App Access**
3. Scroll down and go to **Install unknown apps**
4. Select the app corresponding to your device’s browser (usually Chrome) and enable **Allow from source**

The exact steps to enable APK sideloading may differ based on your device and version of Android.
