-Installation
+## Installation
 ------------
 
 Installation requires the Python developer tools, and wireless_tools package
 for compilation. If Python.h and iwlib.h exist on your system, you should be
 good to go.
 
-    $ pip install iwlib
+`$ pip install iwlib`

+Depending on your linux distro, the package name may change. But this is tested on Ubuntu 17

+## Quick Guide
+--------------
+Run following command in a bash shell to see the available wireless interfaces  
+`$ iwconfig `
+
+('wlan0' is very common, so that is what we will use for this quick guide)  
+
+Now in the python interactive Shell,   
+`>> import iwlib`  
+`>> interface = 'wlan0'`  
+`>> iwlib.get_iwconfig(interface)`  
+` {'BitRate': b'72.2 Mb/s', 'ESSID': b'AP_SSID', 'Access Point': b'AP_MAC', 'stats': {'quality': 45, 'noise': 0, 'updated': 75, 'level': 191}, 'Frequency': b'2.422 GHz', 'Mode': b'Managed'}`
+ 
+The dict's values are byte strings. You can use `b'xyz'.decode('utf-8')` to decode them into python strings.
+
+Finally, here's the docstring for the function  
+`>> print(iwlib.get_iwconfig.__doc__)`  
+` Retrieve the current configuration of an interface. `  
+` Arguments:`  
+`  - device to work on (e.g. eth1, wlan0). `
