-# 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>

-**If you just want a single .js file with the common languages built-in:

-## 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.

-# Work in Progress
+# Leptos Todo App Sqlite with Axum
 
-This example is something I wrote on a long layover in the Orlando airport in July. (It was really hot!)
+This example creates a basic todo app with an Axum backend that uses Leptos' server functions to call sqlx from the client and seamlessly run it on the server.
 
-It is the culmination of a couple years of thinking and working toward being able to do this, which you can see 
-described pretty well in the pinned roadmap issue (#1830) and its discussion of different modes of client-side
-routing when you use islands.
+## Getting Started
 
-This uses *only* server rendering, with no actual islands, but still maintains client-side state across page navigations.
-It does this by building on the fact that we now have a statically-typed view tree to do pretty smart updates with 
-new HTML from the client, with extremely minimal diffing.
+See the [Examples README](../README.md) for setup and run instructions.
 
-The demo itself works, but the feature that supports it is incomplete. A couple people have accidentally
-used it and broken their applications in ways they don't understand, so I've renamed the feature to `dont-use-islands-router`.
+## E2E Testing
+
+See the [E2E README](./e2e/README.md) for more information about the testing strategy.
+
+## Rendering
+
+See the [SSR Notes](../SSR_NOTES.md) for more information about Server Side Rendering.
+
+## Quick Start
+
+Run `cargo leptos watch` to run this example.
