Markdown is a lightweight markup language that is used to format text. It was created by John Gruber in 2004 as a way to write in an easy-to-read and easy-to-write plain text format, and then convert it to structurally valid HTML or other formats.
Markdown is often used for writing on the web, especially on blogs and content management systems, because it allows you to add formatting to your text without using complex coding. For example, you can use Markdown to add headings, emphasis, lists, and links to your text, as well as other formatting like italics and bold text.
To write in Markdown, you simply write your text in a plain text editor, and then use special characters and syntax to add formatting to your text. For example, you can use the "#" character to add a heading, the "*" character to add emphasis, or the ">" character to indent text. Here is an example of some text that is formatted with Markdown:
# Heading This is some *emphasized* text. 1. This 2. Is 3. A 4. List > This is a blockquote. [This is a link](https://www.example.com)
When you convert this text to HTML, it will look like this:
<h1>Heading</h1> <p>This is some <em>emphasized</em> text.</p> <ol> <li>This</li> <li>Is</li> <li>A</li> <li>List</li> </ol> <blockquote> <p>This is a blockquote.</p> </blockquote> <p><a href="https://www.example.com">This is a link</a></p>
As you can see, the Markdown syntax is very simple and easy to read, which makes it a popular choice for writing on the web. There are many variations of the Markdown language, and many different tools and libraries that can be used to convert Markdown to HTML or other formats.
