 There are two basic paths to getting started with Leptos:
 
-1. Client-side rendering with [Trunk](https://trunkrs.dev/)
-2. Full-stack rendering with [`cargo-leptos`](https://github.com/leptos-rs/cargo-leptos)
+1. Client-side rendering with [Trunk](https://trunkrs.dev/) - a great option if you just want to make a snappy website with Leptos, or work with a pre-existing server or 3rd-party API's.
+2. Full-stack / Universal server-side rendering with [`cargo-leptos`](https://github.com/leptos-rs/cargo-leptos) - a great option for building a CRUD-style website or a web-app with Rust powering both frontend and backend. Universal apps rely on either Actix-web or Axum on the server (so you may want to keep their docs handy, too), or you can even go Universal WASM/WASI with the Leptos and Axum integration (more on these options later).

-`cargo-leptos` a little later in this series.
+In Part 1 of this book, we'll start with Client-side rendering Leptos sites and building reactive UI's using `Trunk` to serve our JS+Wasm bundle to the browser.

+We’ll introduce `cargo-leptos` in Part 2 of this book, which is all about working with the full power of Leptos in its Full-stack, SSR mode.

In the guide and examples, you’ll just use the [`ReadSignal::get()`](https://docs.rs/leptos/latest/leptos/struct.ReadSignal.html#impl-SignalGet%3CT%3E-for-ReadSignal%3CT%3E) and [`WriteSignal::set()`](https://docs.rs/leptos/latest/leptos/struct.WriteSignal.html#impl-SignalGet%3CT%3E-for-ReadSignal%3CT%3E) methods instead of calling signal getters and setters as functions.

 Trunk should automatically compile your app and open it in your default browser.
 If you make edits to `main.rs`, Trunk will recompile your source code and
 live-reload the page.
