-node-fetch also supports any spec-compliant FormData implementations such as [formdata-polyfill](https://www.npmjs.com/package/formdata-polyfill). But any other spec-compliant such as [formdata-node](https://github.com/octet-stream/form-data) works too, but we recommend formdata-polyfill because we use this one internally for decoding entries back to FormData.
+node-fetch comes with a spec-compliant [FormData] implementations for posting
+multipart/form-data payloads

-import fetch from 'node-fetch';
-import {FormData} from 'formdata-polyfill/esm.min.js';

-node-fetch also support form-data but it's now discouraged due to not being spec-compliant and needs workarounds to function - which we hope to remove one day
+If you for some reason need to post a stream coming from any arbitrary place,
+then you can append a [Blob] or a [File] look-a-like item.
 
+The minium requirement is that it has:
+1. A `Symbol.toStringTag` getter or property that is either `Blob` or `File`
+2. A known size.
+3. And either a `stream()` method or a `arrayBuffer()` method that returns a ArrayBuffer.
+
+The `stream()` must return any async iterable object as long as it yields Uint8Array (or Buffer)
+so Node.Readable streams and whatwg streams works just fine.
+
+```js
+formData.append('upload', {
+	[Symbol.toStringTag]: 'Blob',
+	size: 3,
+  *stream() {
+    yield new Uint8Array([97, 98, 99])
+	},
+	arrayBuffer() {
+		return new Uint8Array([97, 98, 99]).buffer
+	}
+}, 'abc.txt')
+```

+`fetch` comes with methods to parse `multipart/form-data` payloads as well as
+`x-www-form-urlencoded` bodies using `.formData()` this comes from the idea that
+Service Worker can intercept such messages before it's sent to the server to
+alter them. This is useful for anybody building a server so you can use it to
+parse & consume payloads.
