Just as a cautionary note for

Add how-to guides for extracting temporary credentials to upload/download to a bucket from a local machine

Doing this will always incur cloud egress fees for the project, which can be very large and very quick - https://infrastructure.2i2c.org/topic/billing/chargeable-resources/#egress-fees. For LEAP they hit about 1k$ in less than a day of folks doing that. This is a helpful thing to document, but needs to come with cost warnings around it.

And just to clarify, this only accounts for download - upload is free. Download pricing depends on where they're downloading it to. The cloud billing topic doc linked has more information.
