Update README to reflect changes on not allowing multiple gateways (#11)
Update README to reflect changes on not allowing multiple gateways (#11)

due to https://github.com/cloudflare/react-gateway/commit/4d9f6612dcae0ee0285687d3e0d2ab2472fabe53 only one Gateway is allowed per GatewayDest (which I find slightly inconvenient in my use case, but I assume there was a good reason to do so!)

This PR reflects that change on the README
