 # googlefinance
 Python module to get stock data from Google Finance API
+
+This module provides **no delay**, **real time** stock data in NYSE & NASDAQ.  [yahoo-finance](https://github.com/lukaszbanasiak/yahoo-finance)'s data is delayed by 15 min, but it provides apis to fetch historical day-by-day stock data.
+
+##Install
+From PyPI with pip:
+	
+	$pip install googlefinance
+
+From development repo (requires git)
+
+	$git clone https://github.com/hongtaocai/googlefinance.git
+	$cd googlefinance
+	$python setup.py install
+
+##Usage example
+
+	>>> from googlefinance import getQuotes
+	>>> import json
+	>>> print json.dumps(getQuotes('AAPL'), indent=2)
+	[
+	  {
+    	"Index": "NASDAQ", 
+ 	    "LastTradeWithCurrency": "129.09", 
+        "LastTradeDateTime": "2015-03-02T16:04:29Z",
