+//! The logic to monitor for on-chain transactions and create the relevant claim responses lives
+//! here.
+//!
+//! ChannelMonitor objects are generated by ChannelManager in response to relevant
+//! messages/actions, and MUST be persisted to disk (and, preferably, remotely) before progress can
+//! be made in responding to certain messages, see [`chain::Watch`] for more.
+//!
+//! Note that ChannelMonitors are an important part of the lightning trust model and a copy of the
+//! latest ChannelMonitor must always be actively monitoring for chain updates (and no out-of-date
+//! ChannelMonitors should do so). Thus, if you're building rust-lightning into an HSM or other
+//! security-domain-separated system design, you should consider having multiple paths for
+//! ChannelMonitors to get out of the HSM and onto monitoring devices.
