+## Introduction
+
+This project contains the core of a new introductory guide to Leptos. Pull requests for any typos, clarification, or improvements are always welcome.
+
+You can find the live version of this book on the [Leptos Website](https://book.leptos.dev/).
+
+## Building the Book
+
+It is built using [`mdbook`](https://crates.io/crates/mdbook). You can view a local copy by installing `mdbook` with Cargo.
 
 ```sh
-cargo install mdbook
+cargo install mdbook --version 0.4.*
 ```
 
-This book also uses an mdbook preprocessor called `mdbook-admonish` to style blocks of text like notes, warnings, etc.

-
-Install mdbook admonish using:
 
 ```sh
-cargo install mdbook-admonish
+cargo install mdbook-admonish --version 1.*
 ```
 
+
 and then run the book with
+
 ```sh
 mdbook serve
 ```
 
-It should be available at `http://localhost:3000`.
+It should now be available at [`http://localhost:3000`](http://localhost:3000).
 
+## Optional: VSCode Dev Container
+
+You can optionally build and run it in the example [VSCode Dev Container](https://code.visualstudio.com/docs/devcontainers/containers), which will automatically install all dependencies, build the book, and serve it at [`http://localhost:3000`](http://localhost:3000) with live reloading.
+
+Install Docker and the official [Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension, then open the project in VSCode and "Reopen in dev container" when prompted.
