 # SimpleStockData
 
-SimpleStockData is a simple library providing an API to access basic stock prices.
-You just have to specify a start and an end date, or a specific period, and - if
-needed - a currency to convert all stock prices to.
+SimpleStockData is a wrapper around the yfinance library providing very easy, high-level
+access to the yahoo finance data. It does NOT WRAP all features of yfinance, as this
+would obviously make the whole thing unnecessary. It only provides very basic functionality,
+which is:
 
+1. Grap the history of a specific stock
+2. Select a specific period of time (via parameters `from` and `to`)
+3. Directly convert the data to another currency¹
+
+That's pretty much all. And all this just very convenient.
+
+¹ for example, the given stocks are in different currencies, and you want all of your stocks
+be written to your diagram in the same currency
