\n\n### Chats | Notifications | Users\n\n
\n \n \n \n
\n\n### Settings | Chat | Profile\n\n
\n \n \n \n
\n\n### Firebase\n
\n \n
\n\n## Setup\n#### Requirements\n* Basic knowledge about Android Studio\n* Basic knowledge about Firebase\n\n#### Firebase\n * Setup Authentication and use the Sign-in method 'Email/Password'\n * Setup Realtime Database\n * Setup Storage\n * Replace the file [google-services.json](app/google-services.json)\n * Note: Download the google-services.json file after the Firebase services are set up to automatically include the services in the json file.\n * Note: When updating the google-services.json file then make sure to invalidate the caches as well as doing a clean + rebuild.\n\n#### Project\n1. Download and open the project in Android Studio\n2. Connect your Android phone or use the emulator to start the application\n"
