+Package gun is an implementation of the Gun distributed graph database in Go.
+See https://gun.eco for more information on the Gun distributed graph database.
+
+For common use, create a Gun instance via New, use Scoped to arrive at the
+desired field, then use Fetch to get/listen to values and/or Put to write
+values. A simple example is in the README at https://github.com/cretz/esgopeta.
