[maveraw]

Is there an existing issue for this?

• I have searched the existing issues

Description

Currently, the information in the IntelSGX system seems inadequate. In order for beginners to have a better understanding, we will add more information to the documentation. Hence making it more understandable.

Acceptance Criteria

No response

Suggestions for a technical implementation

Will use some pictorial representation for a better understanding.

Agreed, the SGX set-up is more involved and complicated. There are instructions under the Clouds section here https://enarx.dev/docs/Clouds#other-software. But maybe there should be a generic SGX instruction.
