+Docsify uses [Prism](https://prismjs.com) to highlight code blocks in your pages. Prism supports the following languages by default:
+
+* Markup - `markup`, `html`, `xml`, `svg`, `mathml`, `ssml`, `atom`, `rss`
+* CSS - `css`
+* C-like - `clike`
+* JavaScript - `javascript`, `js`
+
+Support for [additional languages](https://prismjs.com/#supported-languages) is available by loading the language-specific [grammar files](https://cdn.jsdelivr.net/npm/prismjs@1/components/) via CDN:
 
 ```html
-<script src="//cdn.jsdelivr.net/npm/docsify/lib/docsify.min.js"></script>
-<script src="//cdn.jsdelivr.net/npm/prismjs/components/prism-bash.min.js"></script>
-<script src="//cdn.jsdelivr.net/npm/prismjs/components/prism-php.min.js"></script>
+<script src="//cdn.jsdelivr.net/npm/prismjs@1/components/prism-bash.min.js"></script>
+<script src="//cdn.jsdelivr.net/npm/prismjs@1/components/prism-php.min.js"></script>
 ```
 
-To use the new languages, make sure the code block label matches the part after `prism-` in the file name. FOr example, for `prism-bash.js` write a code block labeled with `bash` like this:
+To enable syntax highlighting, wrap each code block in triple backticks with the [language](https://prismjs.com/#supported-languages) specified on the first line:
 
 ````
+```html
+<p>This is a paragraph</p>
+<a href="//docsify.js.org/">Docsify</a>
+```
+
 ```bash
 echo "hello"
 ```
+
+```php
+function getAdder(int $x): int 
+{
+    return 123;
+}
+```
 ````
 
-?> Note that with GitHub-flavored markdown, `sh` and `bash` are effectively aliases of each other, but this is not the case with Prism. So using `sh` will not enable `bash` syntax in this case.
+The above markdown will be rendered as:
 
-For `prism-php.js`, it would be:
+```html
+<p>This is a paragraph</p>
+<a href="//docsify.js.org/">Docsify</a>
+```
+
+```bash
+echo "hello"
+```

 ```php
 function getAdder(int $x): int 
 {

 }
