+## 🚀 Features
+
+- ✅ Windows-like commands (`dir`, `cd`, `mkdir`, `del`, `copy`, `type`, `cls`)  
+- ✅ Extensible via Java classes (easy to add new commands)  
+- ✅ Packaged into `.exe` using **Launch4j**  
+- ✅ Installer wizard using **Inno Setup**  
+- ✅ Works on **Windows** and **Linux** (via `jpackage`)  
+
+---
+
+## 📦 Requirements
+
+To build MyCMD you need:
+
+- [Java JDK 17+](https://adoptium.net/)  
+- [Apache Maven](https://maven.apache.org/)  
+- [Launch4j](https://launch4j.sourceforge.net/) (for `.exe` wrapping)  
+- [Inno Setup](https://jrsoftware.org/isinfo.php) (for Windows installer)  
+
+*(Linux users can use `jpackage` instead of Launch4j/Inno Setup.)*
+
+---
+
+## 🛠️ Build Instructions
+
+### 🔹 Windows
+```bash
+scripts\build-windows.bat
+```
+👆🏻 This will:
+
+- Build the JAR with Maven
+
+- Wrap it into an .exe with Launch4j
+
+- Generate a setup.exe installer with Inno Setup
+
+### Final Output 
+```
+dist/
+ ┣ bin/MyCMD.exe
+ ┣ lib/dependencies.jar
+ ┗ setup.exe
+```
+### Linux 
+```
+chmod +x scripts/build-linux.sh
+./scripts/build-linux.sh
+```
+This will build a `.deb` or `.rpm` package using `jpackage`.
+
+## 🖥️ Usage
+
+After installation, run:
+```
+MyCMD
+```
+
+You can now use commands like:
+```
+> dir
+> cd ..
+> mkdir test
+> echo Hello World!
+> type file.txt
+> del file.txt
+> help
+> exit
+```
+
+## 🧩 Extending MyCMD
+> [!NOTE]
+> There are many commands left like `ls` and `Ping Command`
