 There are three targets:
 - **AlexaSkill**: this is a library with the code that implements the custom Alexa skill. It's a separate library so it can be used by the other two targets. Also, libraries have `ENABLE_TESTABILITY` enabled by default which allows you to use `@testable import` in your unit tests.
 - **Lambda**: The command line executable for deployment to Lambda. This program uses `stdin` and `stdout` for processing data.
-- **Server** (macOS only): To simplify implementing a custom Alexa Skill, the Server target provides an HTTP interface to the AlexaSkill library. This HTTP server can be exposed publicly via [ngrok](https://ngrok.com) and configured in the Alexa console, which enables you to develop and debug an Alexa skill with code running on your development server. This target is macOS only because it wasn't possible to cleanly separate target dependencies and I didn't want to link libraries intended for server development to the Lambda executable.
