+## Getting Started
+
+### Prerequisites
+- Python 3.x
+
+### Installation
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/username/repository-name.git
+   ```
+2. Navigate to the project directory:
+   ```bash
+   cd repository-name
+   ```
+
+---
+
+## Usage
+
+Each script is designed to be run independently. For example, to run the Bubble Sort implementation:
+
+```bash
+python Sorting/BubbleSortImple.py
+```
+
+Most scripts include test cases at the end of the file to demonstrate their functionality.
