-## `nightly` Note
-
-Most of the examples assume you’re using `nightly` version of Rust and the `nightly` feature of Leptos. To use `nightly` Rust, you can either set your toolchain globally or on per-project basis.
-
-To set `nightly` as a default toolchain for all projects (and add the ability to compile Rust to WebAssembly, if you haven’t already):
-
-```
-rustup toolchain install nightly
-rustup default nightly
-rustup target add wasm32-unknown-unknown
-```
-
-If you'd like to use `nightly` only in your Leptos project however, add [`rust-toolchain.toml`](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file) file with the following content:
-
-```toml
-[toolchain]
-channel = "nightly"
-targets = ["wasm32-unknown-unknown"]
-```
-
-The `nightly` feature enables the function call syntax for accessing and setting signals, as opposed to `.get()` and `.set()`. This leads to a consistent mental model in which accessing a reactive value of any kind (a signal, memo, or derived signal) is always represented as a function call. This is only possible with nightly Rust and the `nightly` feature.

 ## `cargo-leptos`
 
 [`cargo-leptos`](https://github.com/leptos-rs/cargo-leptos) is a build tool that's designed to make it easy to build apps that run on both the client and the server, with seamless integration. The best way to get started with a real Leptos project right now is to use `cargo-leptos` and our starter templates for [Actix](https://github.com/leptos-rs/start) or [Axum](https://github.com/leptos-rs/start-axum).
 
 ```bash
 cargo install cargo-leptos

-The new rendering approach being developed for 0.7 supports “universal rendering,” i.e., it can use any rendering library that supports a small set of 6-8 functions. (This is intended as a layer over typical retained-mode, OOP-style GUI toolkits like the DOM, GTK, etc.) That future rendering work will allow creating native UI in a way that is much more similar to the declarative approach used by the web framework.
+The 0.7 update originally set out to create a "generic rendering" approach that would allow us to reuse most of the same view logic to do all of the above. Unfortunately, this has had to be shelved for now due to difficulties encountered by the Rust compiler when building larger-scale applications with the number of generics spread throughout the codebase that this required. It's an approach I'm looking forward to exploring again in the future; feel free to reach out if you're interested in this kind of work.

 - **Performance:** This has huge performance implications: Leptos is simply much faster at both creating and updating the UI than Yew is.
 - **Server integration:** Yew was created in an era in which browser-rendered single-page apps (SPAs) were the dominant paradigm. While Leptos supports client-side rendering, it also focuses on integrating with the server side of your application via server functions and multiple modes of serving HTML, including out-of-order streaming.
 
-- ### How is this different from Dioxus?
+### How is this different from Dioxus?
 
 Like Leptos, Dioxus is a framework for building UIs using web technologies. However, there are significant differences in approach and features.
 
 - **VDOM vs. fine-grained:** While Dioxus has a performant virtual DOM (VDOM), it still uses coarse-grained/component-scoped reactivity: changing a stateful value reruns the component function and diffs the old UI against the new one. Leptos components use a different mental model, creating (and returning) actual DOM nodes and setting up a reactive system to update those DOM nodes.
 - **Web vs. desktop priorities:** Dioxus uses Leptos server functions in its fullstack mode, but does not have the same `<Suspense>`-based support for things like streaming HTML rendering, or share the same focus on holistic web performance. Leptos tends to prioritize holistic web performance (streaming HTML rendering, smaller WASM binary sizes, etc.), whereas Dioxus has an unparalleled experience when building desktop apps, because your application logic runs as a native Rust binary.

+# 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.

+# Highlight.js CDN Assets
+
+**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>
+https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@latest/build/
+
+**If you just want a single .js file with the common languages built-in:
+<https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@latest/build/highlight.min.js>**
+
+---
+
+## 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.
