Electron Application Menu Working Example

I'm new to Electron and having problems finding a working example of an application menu.

When trying to combine the Quick Start app with the example from the Class: Menu page of the Electron Documentation, nothing seems to happen — chaning the label values has no effect.

Googling raises more questions than it solves — such as, do I need to package my application to effect change in the application menu, or do I need to move my main.js and package.json to $projectRoot/resources/app (and if so, do I need to package it to run it)?

Is there a better way to get the hang of Electron...?

Edit

When I add the below to my app on OSX, the Application menu has one entry — Electron, with one option, Quit:

const electron = require('electron');
var menu = electron.Menu.buildFromTemplate([
    {
        label: 'Electron',
        submenu: [
        {
            label: 'Options',
            click: function() {
                alert('Test');
            }
        }
        ]
    }
]);

electron.Menu.setApplicationMenu(menu);

You don't need to package your app to change the application menu. Check that you're calling Menu.setApplicationMenu() after the ready event is emitted, e.g.

app.on('ready', () => {
  const menu = Menu.buildFromTemplate(template)
  Menu.setApplicationMenu(menu)
})
