+## Introduction
+**As a Data Scientist , You may not stick to data format.** 
+
+PDFs is good source of data, most of the organization release their data in PDFs only. **As AI is growing, we need more data for prediction and classification**; hence, ignoring PDFs as data source for you could be a blunder. 
+
+*As you know PDF Processing comes under text analytics.*
+
+
+Most of the Text Analytics Library or frameworks are designed in Python only, this gives a leverage on text analytics. One more thing you can never process a pdf directly in exising frameworks of Machine Learning or Natural Language Processing. Unless they are proving explicit interface for this, **we have to convert pdf to text first.**
+## Problematic
+Most Python Liabiries for Pdf Processing such as PyPDF2 and Pdfminer.six perform in text extraction task, but this performance is limited to a sample PDF document.
+
+That's why, **PDFs-TextExtract** project developed to **extract text from multiple and large pdf documents.**
 
 ## Setup Environment
-- **Step 1:** Select Version of Python to Install from Python.org website.
+
+- **Step 1:** Select Version of Python (Python 3.7) to Install from [Python.org](https://www.python.org/) website.
 - **Step 2:** Download Python Executable Installer.
 - **Step 3:** Run Executable Installer.
 - **Step 4:** Verify Python Was Installed On Windows.
 - **Step 5:** Verify Pip Was Installed.
 - **Step 6:** Add Python Path to Environment Variables (Optional).
-- **Step 7:** Install Python extension for your IDE.
-- **Step 8:** Now you’ll be able to execute python scripts with your IDE.
-- **Step 9:**  *Terminal* : pip install pdfminer.six
-- **Step 10:** *Terminal* : pip install PyPDF2
+- **Step 7:** Install Python extension for your IDE (Visual Studio Code).
+- **Step 8:** Now you’ll be able to execute python scripts with your IDE (Visual Studio Code).
+- **Step 9:**  Execute *Terminal command* inside Python IDE : **pip install pdfminer.six**
+- **Step 10:** Execute *Terminal command* inside Python IDE : **pip install PyPDF2**
 
+## Usage 
+- **Step 1:** Open **..\PDFs-TextExtract\samples** folder and put your PDF Documents inside.
+- **Step 2:** Execute **..\PDFs-TextExtract\Scripts\merged.py** script.
+- **Step 3:** Execute **..\PDFs-TextExtract\Scripts\spliter.py** script.
+- **Step 4:** Execute **..\PDFs-TextExtract\Scripts\extract_text.py** script.
+- **Step 5:** Open **..\PDFs-TextExtract\output** and you will find the result there.
