+# Overview
+[ExtractTable](https://extracttable.com) - **API to extract tabular data from images and scanned PDFs**
+
+The motivation is to make it easy for developers to extract tabular data from images or scanned PDF files without worrying about the table area, column coordinates, rotation et al.
+
+# Prerequisite
+
+Before we talk/boast about the service, a developer MUST need an API key to use the ExtractTable service. [FREE credits here](https://extracttable.com/trail.html). 
+
+We beat this market **not just in accuracy also in cost, and expiration**. You are most welcomed to [BUY credits here](https://extracttable.com/#pricing) or email me at saradhi@extracttable.com for assistance.
+
+
+# Installation
+
+`pip install -U ExtractTable`
+
+
+# Basic Usage
+Ok, enough selling. Let the ease in coding do the talk, and the output encourages you to buy credits - put that timer on and count the LOC.
+
+```python
+from ExtractTable import ExtractTable
+et_sess = ExtractTable(api_key=YOUR_API_KEY)        # Replace your VALID API Key here
+print(et_sess.check_usage())        # Checks the API Key validity as well as shows associated plan usage 
+table_data = et_sess.process_file(filepath=Location_of_Image_with_Tables, output_format="df")
+```
+[Detail Code Here](ExampleCode.ipynb)
+
