+- This should display the version of Node.js, e.g., `v18.12.1`.
+3. Next, check if npm (Node Package Manager) is installed:
+
+npm -v
+
+- This should show a version like `8.19.2`. npm is used to install packages and dependencies.
+
+If you see the versions printed, congratulations—Node.js is set up successfully!

+### Step 4: Set Up a Simple Project (Optional Hands-On)
+To make this more practical, let's create a simple "Hello World" project:
+1. In your terminal, create a new directory:
+
+mkdir my-first-node-project cd my-first-node-project
+
+2. Create a new file called `app.js` using your code editor:
+
+echo 'console.log("Hello, Node.js!");' > app.js
+
+3. Run the file with Node.js:
+
+node app.js
+
+4. You should see: `Hello, Node.js!` printed in the terminal.

+## Troubleshooting Common Issues
+- **Error: 'node' is not recognized**: Ensure Node.js was added to your system's PATH during installation. Restart your terminal or computer and try again.
+- **Permission errors on macOS/Linux**: If you encounter issues, try running commands with `sudo`, but be cautious.
+- **Version mismatches**: If the versions don't match, double-check the installation or reinstall from the official site.
