+## FAQs
+1. The application throws _keystore_ file not found error. How do I fix this?
+	> _keystore_ file is used to digitally sign an Android application and hence, it is not provided with the project. One must create their own _keystore_ file using the [Android KeyTool](https://developer.android.com/studio/publish/app-signing) which comes with the Android Studio in order to sign the APK.
 
-6. After flashing is complete, the device will boot into **onecourse** setup. Follow the [setup instructions](SETUP.md).
+2. How to enable the _Build variant_ option in the _Build_ menu?
+	> The _Build variant_ option is enabled only when the module's gradle file is opened.
