Create GitHub Pages like this one: jspowerx.github.io, and clone packages/helloworld directory.
Create manifest.json inpackages/helloworld directory, and create directory for each menu item withmenu id.

{
    "name":"Hello world",
    "version":"1.0",
    "author":"Your Name",
    "website":"https://yourwebsite.com",
    "description":"Your awesome package description",
    "menu":[
        {
            "id":"hello",
            "title":"Say Hello",
            "shortcut":"cmd+shift+h"
        }
    ]
}
