Issues with setup

[vpavlin]

1. The UCAN script does not work, had to tweak it (I guess you could still change it to actually use a PK, but I am not sure it is needed if the goal is to just generate some unique UCAN?):

import * as ucans from "@ucans/ucans";

(async () => {
  // creating key pair from private key
  const keyPair = await ucans.EdKeypair.create();
  const did = keyPair.did();
  console.log("Generated DID from private key:", did);
})();

2. Might make sense to provide a hint on running redis - e.g.

podman run -d   --name redis_server   -v $PWD/redis-data:/var/redis/data    -p 6379:6379   redis 

3. same for mongo:

podman run --name mongod -d -p 27017:27017 -v ${PWD}/mongodb:/data/db:Z mongo

4. Can I use a public RPC_URL from ChainList (seems I can?:)
