how do I make it work?

You can host the file wherever you wish (Google drive, CDN, etc.) and simply link to it, or even easier is Next exposes files in the /public directory. That means you can put the resume file (pdf recommended) in the /public directory and when deployed, it will be available at https://{yourdomain.com}/{name of resume file}

I'll add this to the readme and include a resume as soon as I get a chance.
