 ## Building the examples
 
 Each example in this repository contains build and deployment instructions, however there are a couple common steps needed for many of the examples included below:
 
-1. Install the latest downloadable 'main' [Development Snapshot](https://www.swift.org/install/macos/#development-snapshots) from swift.org to use Embedded Swift. Public releases of Swift do not yet support Embedded Swift.

+
+## Overview
+
+Embedded Swift is an experimental and rapidly developing feature of the Swift language, as such it is only available in "Development Snapshot". 
+
+The best way to install Swift is using [`swiftly`](http://github.com/swiftlang/swiftly), the official Swift toolchain installer and manager. For instructions on how to install `swiftly`, check out the [Getting Started](https://www.swift.org/swiftly/documentation/swiftly/getting-started) guide.
+
+> Note: Swiftly installs the latest release toolchain during `swiftly init`, if you only plan on using Embedded Swift, you can avoid downloading this toolchain by using the `swiftly init --skip-install` option. 
+
+After installing Swiftly, install the latest main "Development Snapshot" toolchain available for your platform by running:
+
+```shell
+$ swiftly install main-snapshot
+...
+main-snapshot-2025-04-12 installed successfully!
+```
+
+To test that you have Swift installed, run `swift --version` from your shell or terminal app. It should say "6.2-dev", meaning you have a "Development Snapshot" toolchain.
+
+```shell
+$ swift --version
+Apple Swift version 6.2-dev (LLVM 81ab6d9f7e4810f, Swift 9cc1947527bacea)
+Target: arm64-apple-macosx15.0
+Build config: +assertions
+```
+
+> Warning: When using other shells, like one integrated into an IDE, be careful to verify that the version of Swift reported matches that of the shell you used to install Swift.
