Thanks for raising this!

I'm wondering could we maybe switch the order of the options so that the AWS S3 one is first and the MinIO is second? I think it would be great to encourage users to try to get as close to the setup we have as much as possible, while the MinIO option could be present for users who would like to explore a different option.

I'm also a little hesitant to recommend MinIO as the primary method for local development, OS type, since at the moment we only have docs for Linux. Maybe we could rephrase this?

Yeah sure we can switch the order of aws s3 and minio since it would be more relevant, also minio actually does have docs and download for windows so we could either give the docs link to setup minio in windows mention or explicitly say the setup for windows

For the section regarding cloud storage costs, I believe that creating an AWS account and S3 bucket is free and does not require any additional costs, but I might need to double check!

Thanks for working on this! I added in a few notes on option order and recommendation, but I think overall this looks great!
