+# Leptos Hacker News Example with Axum
+
+This example creates a basic clone of the Hacker News site. It showcases Leptos' ability to create both a client-side rendered app, and a server side rendered app with hydration, in a single repository. This repo differs from the main Hacker News example by using Axum as it's server.
+
+## Getting Started
+
+See the [Examples README](../README.md) for setup and run instructions.
