+# Guide to Node.js Installation on Ubuntu 22.04
+
+Node.js is a popular open-source JavaScript runtime built on Chrome's V8 JavaScript engine. It allows you to build scalable and high-performance server-side applications using JavaScript. This guide will walk you through the installation process of Node.js 18 on Ubuntu 22.04.
+
+## Prerequisites
+
+- A system running Ubuntu 22.04
+- A user account with sudo privileges
+- An internet connection
+
+## Installation Steps
+
+Begin by updating your apt repository to ensure you have the latest package information and dependencies. Open a terminal and run the following command:
+
+```bash
+sudo apt update
+```
+
+This command will refresh the package lists and update any outdated packages on your system.
+
+Install the curl utility if it's not already installed. curl is used to transfer data to or from a server using various protocols. Execute the following command in the terminal to install it:
+
+```bash
+sudo apt install curl
+```
+
+This command will download and install curl from the Ubuntu repositories.
+
+Now, you can proceed with the installation of Node.js. Run the following command in the terminal to download and execute the Node.js setup script: **(replace "version" with the version you want to install, e.g. 18)**
+
+```bash
+curl -fsSL https://deb.nodesource.com/setup_version.x | sudo -E bash -
+```
+
+This command fetches the setup script from the NodeSource repository and pipes it to the bash shell with elevated privileges (sudo), allowing it to modify system files.
+
+Once the setup script has been executed, you can install Node.js 18 by running the following command:
+
+```bash
+sudo apt install -y nodejs
+```
+
+This command installs Node.js and its package manager, npm, using the package manager apt.
+
+After the installation is complete, you can verify the Node.js and npm versions by running the following commands:
+
+```bash
+node --version
+npm --version
+```
+
+You should see the version numbers of Node.js and npm printed in the terminal, indicating a successful installation.
+
+## Finished
+
+Congratulations! You have now installed Node.js 18 on your Ubuntu 22.04 machine. Node.js is ready to be used for developing your JavaScript applications.
