How do I add text for instructions like in FPS tutorial?

Hey, I have a quick question, in the first-person movement tutorial, displays text that gives instructions.
How do I do that, when I made a folder that said instructions and pasted the code Into the file it said that it was all wrong. Any ideas?

It doesn’t make sense, also it says you need to import new ammo. I am new to Java, I am trying to learn it, but I still don’t know. I understand if you can’t reply, this is and old conversation. -Blackout_Studio

Well for one ur making the html in a js file, and how they did it is in the html file they made the actual stuff they want in the page then in a css file they styled a ui tag, they they used a script to put it on the screen:

var Ui = pc.createScript('ui');

Ui.attributes.add('html', {
    type: 'asset',
    assetType: 'html'

Ui.attributes.add('css', {
    type: 'asset',
    assetType: 'css'

// initialize code called once per entity
Ui.prototype.initialize = function() {
    var div = document.createElement("div"); = "ui";
    div.innerHTML = this.html.resource;

    style = pc.createStyle(this.css.resource);
