-You can also pass optional arguments to `@fastify/busboy` when registering with Fastify. This is useful for setting limits on the content that can be uploaded. A full list of available options can be found in the [`@fastify/busboy` documentation](https://github.com/fastify/busboy#busboy-methods).
+**Note** about `data.fields`: `busboy` consumes the multipart in serial order (stream). Therefore, the order of form fields is *VERY IMPORTANT* to how `fastify-multipart` can display the fields to you.
+We would recommend you place the value fields first before any of the file fields.
+It will ensure your fields are accessible before it starts consuming any files.
+If you cannot control the order of the placed fields, be sure to read `data.fields` *AFTER* consuming the stream, or it will only contain the fields parsed at that moment.
 
-**Note**: if the file stream that is provided by `data.file` is not consumed, like in the example below with the usage of pump, the promise will not be fulfilled at the end of the multipart processing.
-This behavior is inherited from [`@fastify/busboy`](https://github.com/fastify/busboy).
