document API

[nichoth]

Should add docs to the readme about how to use this

const { system } = require('@socketsupply/ssc-node')

system.receive = async (command, value) => {
}

I think that we need a better API like socket.onMessage(async (command, value) => {})
Also since we made some renaming recently, I think that socket-node would be a better name. WDYT?

👍 That name is good.
