-# Leptos Axum JS SSR Example
-
-This example shows the various ways that JavaScript may be included into
-a Leptos application.  The intent is to demonstrate how this may be done
-and how it may cause the application to fail in an unexpected manner if
-done incorrectly.
-
-## Quick Start
-
-Run `cargo leptos watch` to run this example.

-**Note: this contains only a subset of files from the full package from NPM.**
-
-[![install size](https://packagephobia.now.sh/badge?p=highlight.js)](https://packagephobia.now.sh/result?p=highlight.js)
-
-**This package contains only the CDN build assets of highlight.js.**
-
-This may be what you want if you'd like to install the pre-built distributable highlight.js client-side assets via NPM. If you're wanting to use highlight.js mainly on the server-side you likely want the [highlight.js][1] package instead.
-
-To access these files via CDN:<br>

-## Highlight.js
-
-Highlight.js is a syntax highlighter written in JavaScript. It works in
-the browser as well as on the server. It works with pretty much any
-markup, doesn’t depend on any framework, and has automatic language
-detection.
