[Paid] Google Adsense Plugin Installation

I need to install Google Adsense on our discourse forum hosted on digitalocen. Please let me know the requirements and costing.

There already exists Unofficial Google AdSense plugin and that is really straight-forward to install, see the Docker part of the README.md (on the github repo)

I know the plugin is already available and is simple. However i have never user this type of hosting and do not want to mess with my site or its setup. I need someone to help me out for this.
