 Synopsis
 --------
 
-The :program:`mongorestore` utility provides the ability to import content
-from binary database dump into a specific database. This is the
-inverse functionality of :program:`mongodump`.
+The :program:`mongorestore` tool imports content from binary database
+dump into a specific database. :program:`mongorestore` can import
+content to an existing database or create a new one.
+
+Specifically, :program:`mongorestore` takes the output from
+:program:`mongodump` and restores it. :program:`mongorestore` creates
+indexes on a restore. :program:`mongorestore` performs only inserts. If
+existing data with the same ``_id`` already exists on the database,
+:program:`mongorestore` will not replace it.
+
+The :program:`mongorestore` tool does "fire-n-forget" inserts and does
+not perform safe writes. Any errors that might happen during inserts are
+recorded only on the server logs and not reported in the tool.
