 ## Design overview
 
-Confidential computing projects are largely defined by what is inside the enclave and what is not.
-For Confidential Containers, the enclave contains the workload pod and helper processes and daemons that facilitate the workload pod.
-Everything else, including the hypervisor, other pods, and the control plane, is outside of the enclave and untrusted.

 Confidential Containers also provides components inside the guest and elsewhere to facilitate attestation.
 Attestation is a crucial part of confidential computing and a direct requirement of many guest operations.
 For example, to unpack an encrypted container image, the guest must retrieve a secret key.
-Inside the guest the **confidential-data-hub** and **attestation-agent** handle operations involving secrets and attestation.
+Inside the guest the **Confidential Data Hub (CDH)** and **Attestation Agent (AA)** handle operations involving secrets and attestation.
 Again, these components are beyond the scope of traditional Kata deployments and are located in the ["guest components"](https://github.com/confidential-containers/guest-components) repository.
 
 The CDH and AA use the KBS Protocol to communicate with an external, trusted entity.
