+Generate and build AMD-SEV-SNP attestable VM disk images for GCP or Azure
+
+## Dependencies
+
+To run build and upload disk images, you'll need
+- [packer](https://developer.hashicorp.com/packer/tutorials/docker-get-started/get-started-install-cli)
+- [gcloud](https://cloud.google.com/sdk/docs/install-sdk) (to make GCP disk images)
+- [az](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli) (to make Azure disk images)
+
+Then you'll also need to install the `qemu` plugin for packer, run
+```
+packer init template.pkr.hcl
+```
+
+Finally, you'll have to configure credentials and projects for the cloud provider you want to build
+disk images on. See azure_config.example or gcp_config.example.
+
+## Building
+
+`make build/gcp_version` will create a GCP disk image 
+`make build/azure_version` will create an Azure disk image 
+`make` will default to the GCP version
