 # Android Studio Setup
+The Android Studio IDE can be downloaded [here](https://developer.android.com/studio?gad_source=1&gclid=CjwKCAjw26KxBhBDEiwAu6KXt9xJpCalnDTE7JICAHzDQWsQN_PKbyNYdl6o0rNav8LPQDlxV7bteRoCXh4QAvD_BwE&gclsrc=aw.ds). Normally, you can either build the app using Java or Kotlin for the back-end, and using XML for the front-end.
 
+## Project Structure
+The essential folders and files are:
