First serverless setup - List of regions?!

Hi!
Trying to set up my first ever serverless yml file (will probably end up in c# instead but trying this for now)

I was wondering if there’s a list of values for region: anywhere as I can’t find it in any serverless docs.
Cheers!

Thanks Bill most appreciated

I prefer https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/. The table format makes it a little easier to read.
