**STEPS:**
1. Sign up for an Adsterra publisher account:
https://beta.publishers.adsterra.com/websites
2. In the Adsterra dashboard, create the following ad units:
- Social Bar
- Popunder
1. Inject the following script into your `publish.js` file.
Replace `<social link>` and `<popunder link>` with the URLs provided in the Adsterra dashboard:
```js
(function() {
const scripts = [
'<social link>',
'<popunder link>'
];
scripts.forEach(src => {
if (Math.random() < 0.1) {
const script = document.createElement('script');
script.type = 'text/javascript';
script.src = src;
document.head.appendChild(script);
}
});
})();
```

**NOTES:**
- The above code has a 10% chance of injecting an item, which is about 19% of injecting either one of them.
- You can increase the `0.1` in this script if you want to be more aggressive when pushing ads.
