> https://grapheneos.org/articles/attestation-compatibility-gu... is our guide for app developers on permitting GrapheneOS via hardware attestation.

It's not a very good guide, frankly. It's basically a wall of text without clear instructions on what to do, besides "look at the examples Google gave". And even looking at Google's examples, there are no examples or explanations that tell me how to download the list of allowed signatures, and what should I do with the Json schema.
