Welcome to Hex-Computer Classroom (Sample Tutorial)

Introduction

This is a sample tutorial that demonstrates how a post looks on the site. Each post maps to a YouTube video, shown at the top of the article, followed by the full Markdown tutorial.

Step 1: Write clear steps

Just write each step in Markdown — headings, lists, tables and quotes are all supported.

console.log('Hello, Hex!');

Step 2: Add images

Drop images into this episode’s Images_attachments/ folder and reference them by relative path:

![diagram](./Images_attachments/demo.png)

Step 3: Copyable code

Hover over a code block and a “复制 / Copy” button appears in the top-right corner.
