+# Lite-Shell
+
+Lite-Shell is a lightweight shell implementation written in C. This project demonstrates fundamental concepts of shell programming, including process creation, command parsing, and execution.
+
+## Features
+
+- Execute basic shell commands
+- Support for built-in commands
+- Customizable through source code modifications
+
+## Project Structure
+```python
+lite-shell/
+│
+├── src/ # Source files
+│ ├── main.c # Main entry point
+│ ├── command_exec.c # Command execution logic
+│ ├── history_log.c # History Log logic
+│ └── pipe_redirect.c # Pipe and redirect symbol logic
+│
+├── include/ # Header files
+│ ├── command_exec.h
+│ ├── history_log.h
+│ └── pipe_redirect.h
+│
+├── build/ # Build directory (generated)
+│ ├── lite-shell # Compiled executable
+│ └── obj/ # Object files
+│
+├── Makefile # Makefile for the project
+└── README.md
+```
+## Requirements
+
+- GCC (GNU Compiler Collection)
+
+## Building the Project
+
+To build the project, simply run this at repo's root directory:
+
+```bash
+make
+```
+
+This command will compile the source files and create an executable named lite-shell in the build directory.
+
+## Running Lite-Shell
+After building the project, you can run the shell using:
+
+```bash
+./build/lite-shell
+```
+Cleaning the Build
+To clean up the build files, run:
+
+```bash
+make clean
+```
+This command will remove the build directory and all compiled files.
