+/// `phantom_route_hints` parameter:
+/// * Contains channel info for all nodes participating in the phantom invoice
+/// * Entries are retrieved from a call to [`ChannelManager::get_phantom_route_hints`] on each
+/// participating node
+/// * It is fine to cache `phantom_route_hints` and reuse it across invoices, as long as the data is
+/// updated when a channel becomes disabled or closes
+/// * Note that if too many channels are included in [`PhantomRouteHints::channels`], the invoice
+/// may be too long for QR code scanning. To fix this, `PhantomRouteHints::channels` may be pared
+/// down
+///
+/// `payment_hash` and `payment_secret` come from [`ChannelManager::create_inbound_payment`] or
+/// [`ChannelManager::create_inbound_payment_for_hash`]. These values can be retrieved from any
+/// participating node.
+///
+/// Note that the provided `keys_manager`'s `KeysInterface` implementation must support phantom
+/// invoices in its `sign_invoice` implementation ([`PhantomKeysManager`] satisfies this
+/// requirement).
