 At its bone a `Money` class for Python 3.x. This is a library to be used by backend and frontend API coders of fintech companies, web merchants and subscription services. A simple, yet powerful way of coding with money.
 
+The `stockholm.Money` object has full arithmetic support together with `int`, `float`, `Decimal`, other `Money` objects as well as `string`. `stockholm.Money` object also supports complex string formatting functionality for easy debugging and a clean coding pattern.
+
 ### Installation with `pip`
-``` 
+```
 $ pip install stockholm
 ```
 
 ### Examples
+Full arithmetic support with different types, backed by `Decimal` for dealing with rounding errors, while also keeping the monetary amount fully currency aware.
 ```python
 from stockholm import Money
 
-# Example code in development
+money = Money("4711.50", currency="SEK")
+print(money)
+# 4711.50 SEK
+
+output = (money + 100) * 3 + Money(50)
+print(output)
+# 14484.50 SEK
+
+print(output / 5)
+# 2896.90 SEK
+
+print(round(output / 3, 4))
+# 4828.1667 SEK
+
+print(round(output / 3, 1))
+# 4828.20 SEK
+```
+
+Advanced string formatting functionality
+```python
+from stockholm import Money
+
+jpy_money = Money(1352953, "JPY")
+exchange_rate = Money("0.08861326")
+sek_money = Money(jpy_money * exchange_rate, "SEK")
+
+print(f"I have {jpy_money:,.0m} which equals around {sek_money:,.2m}")
+print(f"The exchange rate is {exchange_rate} ({jpy_money:c} -> {sek_money:c})")
+# I have 1,352,953 JPY which equals around 119,889.58 SEK
+# The exchange rate is 0.08861326 (JPY -> SEK)
+
+print(f"{jpy_money:.0f}")
+# 1352953
+
+print(f"{sek_money:.2f}")
+# 119889.58
+
+print(f"{sek_money:.1f}")
+# 119889.6
+
+print(f"{sek_money:.0f}")
+# 119890
+```
+
+Flexible ways for assigning values to a monetary amount
+```python
+from decimal import Decimal
+from stockholm import Money
+
+Money(100, currency="EUR")
+# <stockholm.Money: "100.00 EUR">
+
+Money("1338 USD")
+# <stockholm.Money: "1338.00 USD">
+
+Money("0.5")
+# <stockholm.Money: "0.50">
+
+amount = Decimal(5000) / 3
+Money(amount, currency="XDR")
+# <stockholm.Money: "1666.666666667">
+
+money = Money("0.30285471")
+Money(money, currency="BTC")
+# <stockholm.Money: "0.30285471 BTC">
+
+cents_as_str = "471100"
+Money(cents_as_str, currency="USD", is_cents=True)
+# <stockholm.Money: "4711.00 USD">
+```
+
+Adding several monetary amounts from a list
+```python
+from stockholm import Money
+
+amounts = [
+    Money(1),
+    Money("1.50"),
+    Money("1000"),
+]
+
+# Use Money.sum to deal with complex values of different data types
+Money.sum(amounts)
+# <stockholm.Money: "1002.50">
+
+# Built-in sum may also be used (if only working with monetary amounts)
+sum(amounts)
+# <stockholm.Money: "1002.50">
 ```
