+## Shortcodes in encrypted Content
+
+{{< version 0.2.8 >}}
+
+`script` is a shortcode to insert custom **:(fa-brands fa-js fa-fw): Javascript** in your post.
+
+{{< admonition >}}
+The script content can be guaranteed to be executed in order after all third-party libraries are loaded. So you are free to use third-party libraries.
+{{< /admonition >}}
+
+Example `script` input:
+
+```go-html-template
+{{</* script */>}}
+console.log('Hello FixIt!');
+{{</* /script */>}}
+```
+
+You can see the output in the console of the developer tool.
+
+{{< script >}}
+console.log('Hello FixIt!');
+{{< /script >}}
