 The function ``makeTransferTransaction()`` needs following parameters:
 
-- Unspent transaction: Previous transaction you have control over (i.e. can fulfill its Output Condition)
-- Metadata for transaction (e.g. price of sold bike)
+- Unspent outputs: Array of `unspent transactions outputs`. Each item contains `Transaction` itself and index of `unspent output` for that `Transaction`.
 - Array of output objects to add to the transaction: Think of these as the recipients of the asset after the transaction. For `TRANSFER` transactions, this should usually just be a list of outputs wrapping Ed25519 conditions generated from the public keys of the recipients.
-- Indices of the outputs in `unspent transaction` that this transaction fulfills.
+- Metadata for transaction (e.g. price of sold bike)

 Fulfill transaction by signing it with Alice's private key.
