-// Client-side field level encryption is a new feature in MongoDB 4.2 that allows specific data fields to be encrypted. Using this
+// MongoDB provides two approaches to In-Use Encryption: Queryable Encryption (QE) and Client-Side Field Level Encryption (CSFLE).
+//
+// The Queryable Encryption and CSFLE features share much of the same API with some exceptions.
+//
+// - The supported algorithms documented in autoencryptionoptions.go do not apply to both features.
+// - SetEncryptedFieldsMap only applies to Queryable Encryption.
+// - SetSchemaMap only applies to CSFLE.
+//
+// In-use encryption is a new feature in MongoDB 4.2 that allows specific data fields to be encrypted. Using this
 // feature requires specifying the "cse" build tag during compilation:
 //
 //	go build -tags cse
 //
 // Note: Auto encryption is an enterprise- and Atlas-only feature.
