Demo 3 Markdown

Learn how to use Markdown, a lightweight markup language ideal for writing documentation, READMEs, and blog posts. Write plain text and see it rendered in real time across GitHub, GitLab, and other platforms.

Why Use Markdown

Markdown is widely supported and easy to learn. It helps you create well-structured documentation with minimal effort.

Headings

Use one to six hash symbols (#) at the start of a line to create headings:

# Heading 1
## Heading 2
### Heading 3
#### Heading 4
##### Heading 5
###### Heading 6

Text and Line Breaks

Write paragraphs by separating text with blank lines. To force a line break within a paragraph, end a line with two spaces:

This is a paragraph describing how Markdown  
handles line breaks.

This is another paragraph.

Emphasis and Lists

You can emphasize text and create different kinds of lists:

Emphasis Types

Unordered Lists

Start lines with -, *, or +:

- Item 1
- Item 2
  - Nested item

Ordered Lists

Use numbers followed by a period:

1. First item
2. Second item

Task Lists (Checkboxes)

Great for tracking progress:

- [ ] Task not completed
- [x] Task completed

Code Formatting

Inline Code

Wrap code snippets in single backticks:

Use inline code to highlight commands or file names.

Code Blocks

Fenced code blocks support syntax highlighting. Specify the language after the opening backticks:

console.log("Hello, world!");

print("Hello, world!")

Links and Blockquotes

Links

Create hyperlinks with the format [link text](URL):

Blockquotes

Use the greater-than sign (>) for quotations:

> This is a blockquote.
> It can span multiple lines.

Now that you’ve mastered Markdown basics, you’re ready to write clear, SEO-friendly documentation for your projects.
