 # Simple Bank
 
-## DB Schema
+This repository contains code for a simple bank service written completely in Go, supporting the following operations:
 
-https://dbdiagram.io/d/Simple-Bank-650d067f02bd1c4a5e0e347d
+1. Create and manage bank accounts, which are composed of owner’s name, balance, and currency.
+2. Record all balance changes to each of the account. So every time some money is added to or subtracted from the account, an account entry record will be created.
+3. Perform a money transfer between 2 accounts. This should happen within a transaction, so that either both accounts’ balance are updated successfully or none of them are.
