Example of Verifiable Credentials

Could you help with an example to replicate the case: Issue, holder, and Verify. The issue creates a Verifiable Credentials and verifies it with ion-cli?

I'm was searching in the ion documentation and w3c but I can't replicate it.

`ion new issue -d d:/dids --curve secp256k1 --kid key-1`
`ion new holder -d d:/dids --curve secp256k1 --kid key-1`
`ion new verify -d d:/dids --curve secp256k1 --kid key-1`

And what are the next steps? Create a DID for the credentials schema? And how I signed like issue and them like holder?

note: Great tool for test and start with DID/ION
