 A budgeting app using Google Sheets as a backing store.
+
+Money Warden stores all your transaction data in a Google Sheet that you create. None of your 
+data is ever sent to any external service except the Google Sheet created _in your Google 
+account_. All the features provided by the app (CRUD transactions, CRUD transaction categories, 
+and everything else) are backed by either the single Google Sheet or by your device's local storage.
+
+This also allows you to run any custom analytics you want on your transactions in an 
+Excel environment, letting you go beyond the standard analytics offered by any budgeting app. 
+You can share your transaction data with others by simply sharing the Google Sheet with them.
+
+Money Warden is completely open source, and all contributions are welcome!
+
+Please report any issues you face or request any new features on this repository's 
+[issues page](https://github.com/hrushikeshrv/money-warden/issues).
