Quickstart for deployment

[tmcw]

It should be possible to do a quickstart for deployment on platforms that support it. This requires:

• A host that can do node
• Postgres

Potential options:

• Deploy to railway button: https://railway.app/button
• Deploy to render button: https://docs.render.com/deploy-to-render
• Guide for deploying to Fly?
• Others?

Probably Vercel isn't an option because no built-in Postgres?
