This teaches you how to run a Gaia storage hub on DigitalOcean (DO). DigitalOcean is an affordable and convenient cloud computing provider. This example uses DigitalOcean Spaces for file storage. A space is equivalent to AWS's S3 file storage solution.
DigitalOcean provides you with a compute machines known as a **Droplets** and storage called a **Spaces**. You need both to run a Gaia hub. The Gaia hub setup you create here, requires get a Digital Droplet with Docker pre-installed and a 250 GB Space. Droplets and storage each run for $5/month or a total of $10/month.

It is important to include the type variable `BooleanCV` in this example, otherwise the typescript type checker won't know which type the list is of and won't enforce homogeneity.
