[browser-sync.js](https://cdn.cacher.io/attachments/u/3ago68caja1c5/bzFc4MHpo5m46G-cPn-bfU-ntMpELydY/browser-sync.js)

```js
const browserSync = require('browser-sync');

const siteUri = 'site.docksal.site'; // <--- Change this

browserSync({
  proxy: siteUri,
  host: siteUri,
  open: 'external',
  files: ['dist/js/**/*.js', 'dist/css/**/*.css'], // <--- Change this
});

```

Adjust the siteUri (no https or http), the css and js output folder.

```
"watch": "concurrently --kill-others \"script to watch\" \"node browser-sync.js\"" // <--- Change this
```

Change "script to watch".
