Introduction to Markdown

Learn the basics of Markdown syntax and how to use it to create content for your Jekyll site.

What is Markdown?

Markdown is a lightweight markup language with plain-text formatting syntax. Its main goal is to be as readable and understandable as possible. Markdown files have the extension .md or .markdown and can be converted into HTML by tools like Jekyll, making it an ideal choice for writing content on the web.

Why Use Markdown?

• Simplicity: Markdown’s syntax is straightforward, making it easy for anyone to learn and use.
• Flexibility: It can be converted into HTML, PDFs, and other formats.
• Compatibility: Markdown files are compatible with version control systems, facilitating collaboration and changes tracking.

The best feature of Markdown is that its just plain text. You can write Markdown in any text editor and there are no special tags to learn or remember, its mostly formatted using punctuation that looks natural.

In Jekyll, Markdown files are processed and converted into HTML, making up the content of your site. You can also use Liquid templating language to incorporate dynamic content into your Markdown files.
