 ## How to use the package
 
 Create a Python file and import the class library from package:
 
-     from rwclib.cRWC5020x import RWCTesterApi
+```python
+from rwclib.cRWC5020x import RWCTesterApi
+```
 
 Create a class object and pass serial port or ethernet port & ip address as constructor parameter
 
-     #Serial Communication
-     ob = RWCTesterApi('COM5') #windows
-     (or)
-     ob = RWCTesterApi('/dev/ttyUSB0') #Linux
-     (or)
-     #Ethernet Communication
-     ob = RWCTesterApi('5001', '192.168.0.33')
-     
+```python
+# ---Serial Communication---
+rwc = RWCTesterApi('COM5') #windows
+(or)
+rwc = RWCTesterApi('/dev/ttyUSB0') #Linux
+
+# ---Ethernet Communication---
+rwc = RWCTesterApi('5001', '192.168.0.33')
+```
+
 Access the class methods using instantiated object
 
-     ob.query_identification()
-     
-To know more about class methods, please see the **code documentation** in the following location in cloned repository:
+```python
