hunk.code_window: ### If you choose to build for Android
   The first time you build the project you will be asked whether you'd like to upload a keystore or have us handle it for you. If you don't know what a keystore is, just leave it to us. Otherwise, feel free to upload your own.
   ```javascript
   [exp] No currently active or previous builds for this project.
   Would you like to upload a keystore or have us generate one for you?
   If you don't know what this means, let us handle it! :)
