+<br><b>ChatApp is a real time one to one chat application with Push Notifications made using Firebase...</b>
+
+Add yours google-services.json
+<br><b> Change Authorization:key with your key from firebase project</b>
+
+<br>Implementation Guide 
+<br>1 - Project
+<br>1 - Open the Project in your android studio;
+<br>2 - *IMPORTANT* Change the Package Name. (https://stackoverflow.com/questions/16804093/android-studio-rename-package)
+
+<br>2 - Firebase Panel
+<br>- Create Firebase Project (https://console.firebase.google.com/);
+<br>- Import the file google-service.json into your project
+<br>- Connect to firebase console authentication and database from your IDE
+<br>- in firebase Storage Rules, change value of "allow read, write:" from "if request.auth != null" to "if true;"
+<br>- For sending notification, paste your Firebase project key into your project APIService.java
+<br>- When you change database settings, you likely will need to uninstall and reinstall apps to avoid app crashes due to app caches.
+
+Check out the design...
