+Importing structured data into the database can be done the following way:
 ```ts
-// pass a filename, the import will be asynchronous
-await db.importJson(filename);
 // pass the object directly, the import will be synchronous
-db.importJson({key: "value"});

+Exporting the data as a JSON object is also possible:
 ```ts
-await db.exportJson(filename[, options]);
+const json = db.toJSON();
 ```
-The file will be overwritten if it exists. The 2nd options argument can be used to control the file formatting. Since `fs-extra`'s `writeJson` is used under the hood, take a look at that [method documentation](https://github.com/jprichardson/node-fs-extra/blob/master/docs/writeJson.md) for details on the options object.
