-_NOTE: The Platform certificate caching service (PCCS) is used to retrieve and cache PCK certificates locally to your cluster from Intel's Platform Certificate Service. This is necessary to attest the authenticity of a TD guest before a workload is started in it. The Quote Generate Service (QGS) runs on the host in a specialized enclave to generate and use TD quotes. For convenient setup these can run inside a Docker container. Learn more at [here]( https://download.01.org/intel-sgx/sgx-dcap/1.17/linux/docs/Intel_TDX_DCAP_Quoting_Library_API.pdf). The PCCS and QGS are used to get Quote for a TD guest. They need to be installed on TDX hosts._
