Markdown provides a syntax for adding links to your documents. This way readers can navigate between pages.
The syntax for creating a link is as follows:
01: [Link text](/path/to/different/page)
The above is equivalent to the following in HTML
01: <a href="/path/to/different/page">Link text</a>
Unfortunately Markdown does not provide anyway to open a page in a new tab. Check out this article to learn about some work arounds.
