 ## Modules Required
 - PyPDF2 - It is used in Python for PDF related operations
 
-## How it Works?
+## AIM
+To build a Python Script using the PyPDF2 Module which can extract text from a PDF file.
+
+## COMPILATION STEPS
 * Import PyPDF2 Module to:-
   * Read the pdf into the program to further manipulate it 
   * Count the number of pages in the PDF
   * Extract the text from a single PDF page
-* Initialize an empty string
-* A for loop parses through each page 
+* Initialize an empty string which will store the text being extracted from the PDF file
+* A for loop is made to parse through each page 
   * The extractText() function is used to extract text from the parsed PDF page
-  * The extracted text is added to the emptry string initialized
+  * The extracted text is added to the emptry string initialized using simple string concatenation
 * After parsing is done, the string in which the extracted text is stored is written in a new file named **extracted_text.txt** using basic File Handling in Python
