 ## 2. Usage

+### 2.1 If used as a Module in Python (via `import`):
+
+If used as a module, all you have to do to access every share you own is
+typing this:
+
+```python
+from SimpleStockData import SSD
+ssd1 = SSD(["EXAMPLE", "ANOTHER TICKER", "..."], "2011-11-11", "2022-02-22", "USD", "Close")
+ssd2 = SSD(["EXAMPLE", "ANOTHER TICKER", "..."], "2011-11-11", "2022-02-22", "USD")  # also working
+ssd3 = SSD(ticker_list = ["EXAMPLE", "ANOTHER TICKER", "..."], period_start="2011-11-11", 
+           period_end="2022-02-22", to_currency="USD", ohcl="Close")  # again working
+```
+
+where...
+
+- `["EXAMPLE", "ANOTHER TICKER", "..."]` is a list of Ticker names (from Yahoo! finance)
+- `2011-11-11` is the start date when accessing price history
+- `2022-02-22` is the end date when accessing price history
+- `USD` is the currency to convert to, later, when dumping history
+- `Close` is **optional**. It specifies which price should be taken per day.<br>
+  Valid values are: `High`, `Low`, `Open`, `Close`
+
+Then you can access the history of the stock just by calling the methods `get_info(index, [key]`
+and `get_history(index, [interval="1d"], [convert=True]`.
+
+It's just that easy.
+
+---
+For more details, look into the [examples](examples) folder at this project's root.

+### 2.2 If used as a CLI:
 TODO; also mention the strange but working GBp thing
 
-### 2.2 If used as a Module in Python (via `import`):
-TODO;
-
+This feature is currently in progress and will soon be available.
