+# OCR Text Extractor
+
+## Overview
+**OCR Text Extractor** is a Python application that allows users to extract text from images using Optical Character Recognition (OCR) via the Tesseract engine. The application provides a simple and user-friendly graphical interface for uploading images, capturing full-screen screenshots, or pasting images from the clipboard to extract text.
+
+## Features
+- **Select Image File**: Choose an image from your computer to extract text from. Supported formats include `.png`, `.jpg`, `.jpeg`, and `.bmp`.
+- **Paste Image from Clipboard**: Take a partial screenshot (e.g., using Windows + Shift + S) and extract text from the image saved in the clipboard.
+- **Capture Full Screen Screenshot**: Capture a screenshot of your entire screen and extract text from it.
+
+## Requirements
+To run this application, you need to have the following installed:
+
+- Python 3.x
+- The following Python packages:
+  - `pytesseract` (Download Tesseract OCR from https://github.com/UB-Mannheim/tesseract/wiki and Add to Environment Path) 
+  - `Pillow` (Python Imaging Library, a fork of PIL)
+  - `Tkinter` (comes pre-installed with Python on most systems)
+
+### Installation of Required Packages
+You can install the required packages using pip:
+
+```bash
+pip install pytesseract Pillow
+```
+
+### How to Run
+```bash
+python main.py
+```
