Take the tutorial!
Modulo is brand new in general, so it's probably brand new to you as well! The Modulo tutorial goes through Modulo basics, starting with HTML and CSS (part 1 and 2), and then JavaScript (part 3).
When keeping your Components in a separate file (e.g. static/components.html), include with the following:
static/components.html
Learn by example?
https://unpkg.com/mdu.js@0.0.36/src/Modulo.js
Or run the following command:
curl https://unpkg.com/mdu.js -o Modulo.js
If you prefer developing using npm, or want to try using Modulo to build an SSG-powered website, then get started with the tiny create-modulo scaffolding tool.
npm
npm init modulo
npx create-modulo
