Document the "full-stack" workload attestation/verification flow #9
Description
This library currently implements integrity attestation/verification for a very small number of layers in a TD's stack. The end goal is to be able to validate any (and all) layers of the hardware and software stack, at the host and guest levels. To this end, we need to add a document to this repo that details a "full-stack" attestation flow, what verifying each layer gets us security-wise, and denotes which features are currently supported.
