    FOLLOW THESE INSTRUCTIONS CAREFULLY!

    (1) Review the Contract Name / Contract Address pairs below and confirm that they match
        the addresses found in the contract artifacts of your current deployment.

    ${namedAddresses
      .map((namedAddress) => {
        const padding = ' '.repeat(40 - namedAddress.name.length)
        return `
        ${namedAddress.name}${padding}  ${namedAddress.addr}
      `
      })
      .join('\n')}

    (2) Review the CURRENT and FINAL AddressManager owners and verify that these are the expected values:

        Current AddressManager owner: (${currentOwner})
        Final AddressManager owner:   (${finalOwner})

        [${
          currentOwner === finalOwner
            ? 'THESE ARE THE SAME ADDRESSES'
            : 'THESE ARE >>>NOT<<< THE SAME ADDRESSES'
        }]

    (3) Transfer ownership of the AddressManager located at (${
      Lib_AddressManager.address
    })
        to the AddressDictator contract located at the following address:

        TRANSFER OWNERSHIP TO THE FOLLOWING ADDRESS ONLY:
        >>>>> (${AddressDictator.address}) <<<<<

    (4) Wait for the deploy process to continue.
