✍️ How to Add Content

Writing a Topic

1. Navigate to the topics/ directory
2. Open the corresponding .md file (e.g., 01-oops.md)
3. Write your content in GitHub Flavored Markdown
4. Commit and push to the main branch
5. GitHub Pages will automatically deploy the changes

Markdown Tips

• Use # for main title, ## for sections, ### for subsections
• Use fenced code blocks with language tags for syntax highlighting:

  int main() {
      return 0;
  }

• Use > blockquote for notes and tips
• Use **bold** and *italic* for emphasis
• Tables, task lists, and other GFM features are fully supported
