+1. Log in to the [Netlify dashboard](https://app.netlify.com/) and click "Add new site".
+2. Select your Git provider and repository containing your Quartz project.
+3. Under "Build command", enter `npx quartz build`.
+4. Under "Publish directory", enter `public`.
+5. Press Deploy. Once it's live, you'll have a `*.netlify.app` URL to view the page.
