Incorrect Documentation

[nil]

The docs here walk through an offline signing scenario with two signers, using a nonce account. There is an issue in the section where the author signs the transaction with the second keypair called sender.json in the scenario. The --fee-payer flag is missing, and I noticed that the co-signer.json's address and signature are missing in the transaction, and that the sender.json's address actually paid the fee.

Sender's address H8BHbivzT4DtJxL4J4X53CgnqzTUAEJfptSaEHsCvg51
Co-sender's address HDx43xY4piU3xMxNyRQkj89cqiF15hz5FVW9ergTtZ7S
