How to configure mathjax?

I want to configure the mathjax with the following scripts:

```

MathJax.Hub.Config({"HTML-CSS": { preferredFont: "TeX", availableFonts: ["STIX","TeX"], linebreaks: { automatic:true }, EqnChunk: (MathJax.Hub.Browser.isMobile ? 10 : 50) },tex2jax: { inlineMath: [ ["$", "$"], ["\\(","\\)"] ], displayMath: [ ["$$","$$"], ["\\[", "\\]"] ], processEscapes: true, ignoreClass: "tex2jax_ignore|dno",skipTags: ['script', 'noscript', 'style', 'textarea', 'pre', 'code']},TeX: { noUndefined: { attributes: { mathcolor: "red", mathbackground: "#FFEEEE", mathsize: "90%" } }, Macros: { href: "{}" } },messageStyle: "none"});

MathJax.Hub.Queue(function() {
var all = MathJax.Hub.getAllJax(), i;
for(i=0; i < all.length; i += 1) {
all[i].SourceElement().parentNode.className += ' has-jax';
}});

```

Where to do this configuration? I add this configuration to `page.st`, but it seems to be not correct.
