How to fork and try the sample?

Hello, I would like to try this repo, the instructions say:
**1. Fork and then clone the repo.
2. Run and try the sample.**

I tried setup it on: apache, node, and arcgis web appbuilder (developer edition). However, none of they work for me.
In apache (httpd) an error occurs when **index.html** require the file **app/welcome.js**
```javascript

require(["c-through/welcome", "dojo/domReady!"],function(Welcome){
var welcome = new Welcome();
welcome.init();
});

```
Help me please @lisastaehli.
