/// `Persist` defines behavior for persisting channel monitors: this could mean
/// writing once to disk, and/or uploading to one or more backup services.
///
-/// Each method can return three possible values:
-/// * If persistence (including any relevant `fsync()` calls) happens immediately, the
-/// implementation should return `Ok(())`, indicating normal channel operation should continue.
-/// * If persistence happens asynchronously, implementations should first ensure the
-/// [`ChannelMonitor`] or [`ChannelMonitorUpdate`] are written durably to disk, and then return
-/// `Err(ChannelMonitorUpdateErr::TemporaryFailure)` while the update continues in the
-/// background. Once the update completes, [`ChainMonitor::channel_monitor_updated`] should be
-/// called with the corresponding [`MonitorUpdateId`].
+/// Persistence can happen in one of two ways - synchronously completing before the trait method
+/// calls return or asynchronously in the background.
+///
+/// # For those implementing synchronous persistence
+///
+/// * If persistence completes fully (including any relevant `fsync()` calls), the implementation
+/// should return [`ChannelMonitorUpdateStatus::Completed`], indicating normal channel operation
+/// should continue.
+///
+/// * If persistence fails for some reason, implementations should consider returning
+/// [`ChannelMonitorUpdateStatus::InProgress`] and retry all pending persistence operations in
+/// the background with [`ChainMonitor::list_pending_monitor_updates`] and
+/// [`ChainMonitor::get_monitor`].
+///
+/// Once a full [`ChannelMonitor`] has been persisted, all pending updates for that channel can
+/// be marked as complete via [`ChainMonitor::channel_monitor_updated`].
+///
+/// If at some point no further progress can be made towards persisting the pending updates, the
+/// node should simply shut down.
+///
+/// * If the persistence has failed and cannot be retried further (e.g. because of an outage),
+/// [`ChannelMonitorUpdateStatus::UnrecoverableError`] can be used, though this will result in
+/// an immediate panic and future operations in LDK generally failing.
+///
+/// # For those implementing asynchronous persistence
+///
+/// All calls should generally spawn a background task and immediately return
+/// [`ChannelMonitorUpdateStatus::InProgress`]. Once the update completes,
+/// [`ChainMonitor::channel_monitor_updated`] should be called with the corresponding
+/// [`MonitorUpdateId`].
+///
+/// Note that unlike the direct [`chain::Watch`] interface,
+/// [`ChainMonitor::channel_monitor_updated`] must be called once for *each* update which occurs.
+///
+/// If at some point no further progress can be made towards persisting a pending update, the node
+/// should simply shut down. Until then, the background task should either loop indefinitely, or
+/// persistence should be regularly retried with [`ChainMonitor::list_pending_monitor_updates`]
+/// and [`ChainMonitor::get_monitor`] (note that if a full monitor is persisted all pending
+/// monitor updates may be marked completed).
+///
+/// # Using remote watchtowers
///
-/// Note that unlike the direct [`chain::Watch`] interface,
-/// [`ChainMonitor::channel_monitor_updated`] must be called once for *each* update which occurs.
+/// Watchtowers may be updated as a part of an implementation of this trait, utilizing the async
+/// update process described above while the watchtower is being updated. The following methods are
+/// provided for bulding transactions for a watchtower:
+/// [`ChannelMonitor::initial_counterparty_commitment_tx`],
+/// [`ChannelMonitor::counterparty_commitment_txs_from_update`],
+/// [`ChannelMonitor::sign_to_local_justice_tx`], [`TrustedCommitmentTransaction::revokeable_output_index`],
+/// [`TrustedCommitmentTransaction::build_to_local_justice_tx`].
///
-/// * If persistence fails for some reason, implementations should return
-/// `Err(ChannelMonitorUpdateErr::PermanentFailure)`, in which case the channel will likely be
-/// closed without broadcasting the latest state. See
-/// [`ChannelMonitorUpdateErr::PermanentFailure`] for more details.
