Options for including mathematics on your website include:

• MathJax
• KaTeX
• TikZJax (GitHub, Demo)
• TeXMe
• jqmath
• AsciiMath

The Nift documentation covers how to display $\LaTeX$ on your websites using MathJax. Repeating the information on this page, using MathJax on your site is as simple as adding the following code to the head of each page:

			<!-- uses MathJax CDN for LaTeX support
				 see https://docs.mathjax.org/en/latest/web/configuration.html for more info -->
			<script id="MathJax-script" async
			        src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js">
			</script>
			<script>
				window.MathJax = {
					tex: {
						inlineMath: [['$', '$'], ['\\(', '\\)']],
						displayMath: [['$$', '$$'], ["\\[", "\\]"]],
						processEscapes: true
					}
				};
			</script>
			

You should then be able to paste $\LaTeX$ equations straight into content files. Both `\$..\$` and `\\(..\\)` work for inline equations, and both `\$\$..\$\$` and `\\[..\\]` work for displayed equations (note inside markdown/showdown blocks use `\\(..\\)` and `\\[..\\]`, or the `$` syntax). Eg. When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are: \[x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}\]

If you want to insert a dollar sign on a page, as opposed to opening/closing an inline equation, use \\$ and MathJax will escape the character.

Note: if you are opening a page locally and are not connected to the internet then MathJax will not load, you will simply see the unprocessed LaTeX equations.
