 - To start development, open the project in Android Studio. Both app (Kotlin/Java) and native (C++/C) source code can be properly developed using the IDE, but *always* use `build.py` for building.
 - `build.py` builds in debug mode by default. If you want release builds (with `-r, --release`), you need a Java Keystore to sign APKs and zips. For more information, check [Google's Documentation](https://developer.android.com/studio/publish/app-signing.html#generate-key).
