+## Overview
+
+This project is a simple Python simulation of Bitcoin mining. It demonstrates the core concepts of blockchain mining, such as generating transactions, calculating hashes, and solving proof-of-work problems by finding a valid nonce.
+
+## Features
+
+-    Random transaction generation.
+-    SHA-256 hashing of block data.
+-    Proof-of-work implementation with adjustable difficulty.
+-    Simulation of blockchain block creation.
+
+## Requirements
+
+-    Python 3.6+
+
+## Installation
+
+1. Clone the repository or download the source code:
+     ```bash
+     git clone <repository-url>
+     ```
+
+## Usage
+
+1. Run the script:
+     ```bash
+     python main.py
+     ```
+2. The program will generate random transactions, mine blocks, and display the resulting hashes.
+
+### Example Output
+
+```
+Mining Block 1 with Transactions: 12345->67890->50; 54321->09876->30; 11111->22222->20
+Block found! Nonce: 45678, Hash: 00000f9d6c24...
+New Hash: 00000f9d6c24...
+```
+
+## Configuration
+
+The script contains configurable constants to adjust the mining simulation:
+
+-    `MAX_NONCE`: Limits the number of nonce iterations for mining. Default is `1,000,000`.
+-    `DIFFICULTY`: Specifies the number of leading zeros required in the hash. Default is `6`.
+
+To modify these values, edit the script directly:
+
+```python
+MAX_NONCE = 1000000  # Set a higher or lower limit as needed
+DIFFICULTY = 6       # Adjust difficulty for faster or slower mining
+```
+
+## Project Structure
+
+-    `mining_simulation.py`: Main script containing all functionality for the simulation.
+
+## How It Works
+
+1. **Transaction Generation**: Random transactions are created with a sender, receiver, and amount of bitcoins.
+2. **Hash Calculation**: Each block is hashed using SHA-256.
+3. **Proof-of-Work**: The script iterates through possible nonce values to find a hash matching the difficulty.
+4. **Blockchain Simulation**: Each block references the previous block's hash, forming a simple blockchain.
+
+## Limitations
+
+-    This is a simplified simulation and does not represent the full complexity of real-world Bitcoin mining.
+-    The script is single-threaded and not optimized for performance.
