You explained "generate a DID document referencing the public key source of the issuing address" like this in readme.
I am going to generate DID document using ethereum source public key in nodejs.

You need to store the secp256k1 key used to derive your ETH address as publicKeyJwk format.

Here is an example of the expected data format: https://www.blockcerts.org/samples/3.0/issuer-blockcerts.json (in verificationMethod, id: https://www.blockcerts.org/samples/3.0/issuer-blockcerts.json#key-1.

So from that, you need to find a library that helps you convert your public key (likely in Hex format) to JWK.

We have this script that helps achieve what you are after so you may find things that will help: https://github.com/blockchain-certificates/did-generator
