+
+The channeldb implements the persistent storage engine for `lnd` and
+generically a data storage layer for the required state within the Lightning
+Network. The backing storage engine is
+[boltdb](https://github.com/coreos/bbolt), an embedded pure-go key-value store
+based off of LMDB.
+
+The package implements an object-oriented storage model with queries and
+mutations flowing through a particular object instance rather than the database
+itself. The storage implemented by the objects includes: open channels, past
+commitment revocation states, the channel graph which includes authenticated
+node and channel announcements, outgoing payments, and invoices
+
