+# Action Form Error Handling Example
 
-# Leptos Starter Template
+## Getting Started
 
-This is a template for use with the [Leptos](https://github.com/leptos-rs/leptos) web framework and the [cargo-leptos](https://github.com/akesson/cargo-leptos) tool.
+See the [Examples README](../README.md) for setup and run instructions.
 
-## Creating your template repo
+## Quick Start
 
-If you don't have `cargo-leptos` installed you can install it with
-
-`cargo install cargo-leptos`
-
-Then run
-
-`cargo leptos new --git leptos-rs/start`
-
-to generate a new project template (you will be prompted to enter a project name).
-
-`cd {projectname}`
-
-to go to your newly created project.
-
-Of course, you should explore around the project structure, but the best place to start with your application code is in `src/app.rs`.
-
-## Running your project
-
-`cargo leptos watch`  
-By default, you can access your local project at `http://localhost:3000`
-
-## Installing Additional Tools
-
-By default, `cargo-leptos` uses `nightly` Rust, `cargo-generate`, and `sass`. If you run into any trouble, you may need to install one or more of these tools.
-
-1. `rustup toolchain install nightly --allow-downgrade` - make sure you have Rust nightly
-2. `rustup target add wasm32-unknown-unknown` - add the ability to compile Rust to WebAssembly
-3. `cargo install cargo-generate` - install `cargo-generate` binary (should be installed automatically in future)
-4. `npm install -g sass` - install `dart-sass` (should be optional in future)
-
-## Executing a Server on a Remote Machine Without the Toolchain
-After running a `cargo leptos build --release` the minimum files needed are:
-
-1. The server binary located in `target/server/release`
-2. The `site` directory and all files within located in `target/site`
-
-Copy these files to your remote server. The directory structure should be:
-```text
-leptos_start
-site/
-```
-Set the following environment variables (updating for your project as needed):
-```sh
-export LEPTOS_OUTPUT_NAME="leptos_start"
-export LEPTOS_SITE_ROOT="site"
-export LEPTOS_SITE_PKG_DIR="pkg"
-export LEPTOS_SITE_ADDR="127.0.0.1:3000"
-export LEPTOS_RELOAD_PORT="3001"
-```
-Finally, run the server binary.
-
-## Notes about CSR and Trunk:
-Although it is not recommended, you can also run your project without server integration using the feature `csr` and `trunk serve`:
-
-`trunk serve --open --features csr`
-
-This may be useful for integrating external tools which require a static site, e.g. `tauri`.
+Execute `cargo leptos watch` to run this example.

 This example uses the basic Hacker News example as its basis, but shows how to run the server side as WASM running in a JS environment. In this example, Deno is used as the runtime.
 
-**NOTE**: This example is slightly out of date pending an update to [`axum-js-fetch`](https://github.com/seanaye/axum-js-fetch/), which was waiting on a version of `gloo-net` that uses `http` 1.0. It still works with Leptos 0.5 and Axum 0.6, but not with the versions of Leptos (0.6 and later) that support Axum 1.0.

+# Leptos Todo App Sqlite with Axum
+
+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.
+
+## Getting Started
+
+See the [Examples README](../README.md) for setup and run instructions.
+
+## 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.
