README.md

@@ -90,35 +90,13 @@ Here are some resources for learning more about Leptos:
 - [API Documentation](https://docs.rs/leptos/latest/leptos/)
 - [Common Bugs](https://github.com/leptos-rs/leptos/tree/main/docs/COMMON_BUGS.md) (and how to fix them!)
 
-## `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
-cargo leptos new --git https://github.com/leptos-rs/start
+cargo leptos new --git https://github.com/leptos-rs/start-axum
 cd [your project name]
 cargo leptos watch

+# E2E Testing
+
+This example demonstrates e2e testing with Rust using executable requirements.
+
+## Testing Stack
+
+|    |      Role      |  Description |
+|---|---|---|
+| [Cucumber](https://github.com/cucumber-rs/cucumber/tree/main) | Test Runner | Run [Gherkin](https://cucumber.io/docs/gherkin/reference/) specifications as Rust tests |
+| [Fantoccini](https://github.com/jonhoo/fantoccini/tree/main) | Browser Client | Interact with web pages through WebDriver |
+| [Cargo Leptos](https://github.com/leptos-rs/cargo-leptos) | Build Tool |  Compile example and start the server and end-2-end tests |
+| [chromedriver](https://chromedriver.chromium.org/downloads) | WebDriver | Provide WebDriver for Chrome |
+
+## Testing Organization
+
+Testing is organized around what a user can do and see/not see. Test scenarios are grouped by the **user action** and the **object** of that action. This makes it easier to locate and reason about requirements.
+
+Here is a brief overview of how things fit together.
+
+```bash
+features
+└── {action}_{object}.feature   # Specify test scenarios
+tests
+├── fixtures
+│   ├── action.rs               # Perform a user action (click, type, etc.)
+│   ├── check.rs                # Assert what a user can see/not see
+│   ├── find.rs                 # Query page elements
+│   ├── mod.rs
+│   └── world
+│       ├── action_steps.rs     # Map Gherkin steps to user actions
+│       ├── check_steps.rs      # Map Gherkin steps to user expectations
+│       └── mod.rs
+└── app_suite.rs                # Test main
