-_**Note:**_ Users on _Linux_ and _MacOS_ are required to add a `sudo` before these commands.
+1. **Install Node.js and npm**  
 
-Check installation using
+   Download and install **Node.js v16** from [Node.js Official Website](https://nodejs.org/). Make sure to include the npm package manager when prompted.

+2. **Install Required Global Packages**
 
-```bash
-v16.14.0
-8.3.1
-Version 4.6.2
-v10.6.0
-v14.1.0
-```
+    Run the following commands:
+
+    ```bash
+    npm i -g http-server
+    npm i -g typescript
+    npm i -g ts-node
+    ```
+
+    _**Note:**_ Users on _Linux_ and _MacOS_ are required to add a `sudo` before these commands.
+
+    ```bash
+    sudo npm i -g typescript ts-node http-server
+    ```
+
+    These global packages are _not required by the app_ but serve as extra utilities.
+
+    **Alternative for Unix-like systems:**
+
+    If Python is installed, users can serve built files with:
+
+    ```bash
+    python3 -m http.server --bind 127.0.0.1 8080
+    ```
+
+3. **Verify Installation**
+
+    Ensure all tools are installed correctly by running:
+
+    ```bash
+    node -v && npm -v && tsc -v && ts-node -v && http-server -v
+    ```
+
+    _**Note:**_  For _Windows OS_, this works only in **PowerShell 7+ (Core)**, not in Windows PowerShell (v5.1 or earlier). To check your powershell version, run `$PSVersionTable` in the integrated terminal. If outdated (below 7.0), run `winget install --id Microsoft.Powershell --source winget` to update. If `winget` is unavailable, download the latest `.msi` installer from the official [PowerShell GitHub releases](https://github.com/PowerShell/PowerShell/releases) based on your system architecture.
