+# 🐚 minishell – Custom UNIX Shell 💻
+
+Welcome to **minishell**, a project that implements a **custom UNIX shell** from the ground up! 🌟 This shell allows for command execution, pipe management, and process handling. 🌐
+
+## 📝 Project Overview
+
+In this project, we create a fully functional **UNIX shell** that supports various commands, piping between processes, and robust error handling. The shell is designed to handle signals 📡 and fork processes efficiently 🍴, simulating the behavior of bash and other traditional UNIX shells. 🚀
+
+### Features:
+- 🔹 **Command execution**: Run shell commands with ease.
+- 🔹 **Pipe management**: Link commands together for streamlined output processing.
+- 🔹 **Signal handling**: Manage signals effectively within the shell environment.
+- 🔹 **Process forking**: Create child processes to execute commands.
+- 🔹 **Error handling**: Robust mechanisms to handle errors gracefully.
+
+## 🛠️ Installation & Setup
+
+To get started, follow these steps to set up and run the project:
+
+1. **Clone the repository**:
+   ```bash
+   git clone https://github.com/mdev9/minishell.git
+   cd minishell
+   make
+   ```
+   
+2. **Run the shell**:
+   ```bash
+   ./minishell
+   ```
+
+## 🔍 Technologies Used
+
+- C 💻: Primary language used to implement the shell.
+- System Calls 📞: Leveraging UNIX system calls for process management and execution.
+- Pipes 🚰: Implementing inter-process communication through pipes.
+- Signals ⚡: Handling OS signals for effective process management.
+
+## 🎯 Goals of the Project
+- Create a functional UNIX shell that mimics common shell behaviors.
+- Understand key operating system concepts such as process management and system calls.
+- Enhance programming skills in C through practical application.
+
+Thank you for checking out minishell! 🌟 Happy coding! 💻
