Outputting "Hello, World!" from WebEngine is as simple as writing the message in the page/index.html file and serving it. Even though this task seems very simplistic, it serves a purpose in acting as a more in-depth guide in setting up the environment for running WebEngine apps, and acts as a basis for the future follow-on tutorials.

Before we jump into setting up the environment, here's a spoiler:

page/index.html

<!doctype html>
<h1>Hello, World!</h1>

Then run gt run from the project root and visit http://localhost:8080 to see your glorious program in action.
