-The Node.js language-specific guide teaches you how to containerize a Node.js application using Docker. In this guide, you’ll learn how to:
+[Node.js](https://nodejs.org/en) is a powerful JavaScript runtime for building scalable, high-performance applications. While it's flexible and fast, managing different development and deployment environments can become complex. Docker offers a solution: a consistent, containerized environment that works everywhere.
 
-- Containerize and run a Node.js application
-- Set up a local environment to develop a Node.js application using containers
-- Run tests for a Node.js application using containers
-- Configure a CI/CD pipeline for a containerized Node.js application using GitHub Actions
-- Deploy your containerized Node.js application locally to Kubernetes to test and debug your deployment

+## What will you learn?
+
+In this guide, you will learn how to:
+
+- Containerize and run a Node.js application using Docker.
+- Run unit tests inside a Docker container.
+- Set up a development container environment.
+- Configure GitHub Actions for CI/CD with Docker.
+- Deploy your Dockerized Node.js app to Kubernetes.
+
+To begin, you’ll start by containerizing an existing Node.js application.
+
+---
+
+## Prerequisites
+
+Before you begin, make sure you're familiar with the following:
+
+- Basic understanding of [JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript) or [TypeScript](https://www.typescriptlang.org/).
+- Basic knowledge of [Node.js](https://nodejs.org/en) and [npm](https://docs.npmjs.com/about-npm) for managing dependencies and running scripts.
+- Understanding of Docker concepts such as images, containers, and Dockerfiles. If you're new to Docker, start with the [Docker basics](/get-started/docker-concepts/the-basics/what-is-a-container.md) guide.
+
+Once you've completed the Node.js getting started modules, you’ll be ready to containerize your own Node.js application using the examples and instructions provided in this guide.
