-# 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.
