${MAKE} ${NBC_BINARY}

To monitor the Eth1 validator deposit contract, you'll need to pair
the Nimbus beacon node with a Web3 provider capable of serving Eth1
event logs. This could be a locally running Eth1 client such as Geth
or a cloud service such as Infura. For more information please see
our setup guides:

  echo -n "Please enter a Web3 provider URL: "
  read WEB3_URL
