+#### Nextras Dbal
+
+You must create a file with specific format in scanned dirs such as **messages.en_US.nextrasdbal**. All parameters are optional, but the file has to exist.
+
+```neon
+table: "my_table" # if you specify table key, "messages" from file name will be ignored
+id: "id" # id column name, default is "id"
+locale: "locale" # locale column name, default is "locale"
+message: "message" # message column name, default is "message"
+```
+
+Add loader to translation configuration:
+
+```neon
+translation:
+	loaders:
+		nextrasdbal: Contributte\Translation\Loaders\NextrasDbal
+```
