+This code creates and submits an order transaction, although the same principles apply to other types of transactions as well. After submitting the transaction, the code uses a new Promise, which queries the ledger again after using setTimeout to wait a fixed amount of time, to see if the transaction has been verified. If it hasn't been verified, the process repeats until either the transaction is found in a validated ledger or the returned ledger is higher than the LastLedgerSequence parameter.
+
+In rare cases (particularly with a large delay or a loss of power), the `rippled` server may be missing a ledger version between when you submitted the transaction and when you determined that the network has passed the `maxLedgerVersion`. In this case, you cannot be definitively sure whether the transaction has failed, or has been included in one of the missing ledger versions. RippleAPI returns `MissingLedgerHistoryError` in this case.
+
+If you are the administrator of the `rippled` server, you can [manually request the missing ledger(s)](rippled-apis.html#ledger-request). Otherwise, you can try checking the ledger history using a different server. (Ripple runs a public full-history server at `s2.ripple.com` for this purpose.)
