 What is data serialization?
 ---------------------------
 
-Data serialization is the concept of converting structured data into a format 
-that allows it to be shared or stored in such a way that its original 
-structure to be recovered. In some cases, the secondary intention of data 
-serialization is to minimize the size of the serialized data which then

 minimizes disk space or bandwidth requirements.
 
 Pickle

         grades = { 'Alice': 89, 'Bob': 72, 'Charles': 87 }
-

         #Use dumps to convert the object to a serialized string
         serial_grades = pickle.dumps( grades )
-       
-        #Use loads to de-serialize an object

+        #Use loads to de-serialize an object
         received_grades = pickle.loads( serial_grades )
 
 Protobuf
 --------
 
-If you're looking for a serialization module that has support in multiple 
-languages, Google's `Protobuf 
-<https://developers.google.com/protocol-buffers>`_ library is an option.
