+Example Usage
+-------------
+
+```python
+from bittrex import Bittrex
+
+my_bittrex = Bittrex(None, None)
+my_bittrex.get_markets()
+{'success': True, 'message': '', 'result': [{'MarketCurrency': 'LTC', ...
+```
+
+To access account methods, an API key for your account is required and can be 
+generated on the `Settings` then `API Keys` page. 
+Make sure you save the secret, as it will not be visible 
+after navigating away from the page. 
+
+```python
+from bittrex import Bittrex
+
+my_bittrex = Bittrex("<my_api_key>", "<my_api_secret>")
+
+my_bittrex.get_balance('ETH')
+{'success': True, 
+ 'message': '',
+ 'result': {'Currency': 'ETH', 'Balance': 0.0, 'Available': 0.0, 
+            'Pending': 0.0, 'CryptoAddress': None}
+}
+```
+
+
+Testing
+-------
+
+
 In order to run the integration tests, a file called "secrets.json" must be added to the test folder.
 Structure it as follows, adding your API keys:
-<pre>
-<code>
+
+```json
 {
   "key": "mykey",
   "secret": "mysecret"
 }
-</code>
-</pre>
+```
