basic usage and setup documents would be useful

Hey I was just poking around at this and checked out https://explore.veramo.dev/connect

I wasn't sure what sort of Agent URL I was supposed to put in here and didn't find any documentation on how to use it. On first go my assumption was that I'd need to setup an agent and connect it to there, but I wasn't sure.

I checked the [dev docs](https://veramo.io/docs/dev_tools/agent_explorer) and found how to start the service locally, but not how to use it. Is there a dependency on another part of the veramo project that I need to start to get this going?
