+-   add `resp.ok` - same as WHATWG fetch `resp.ok = (resp.statusCode >= 200 && resp.statusCode < 300)`
+-   add `resp.stream.body()` to populate `resp.body` rather than (or perhaps in addition to) continuing to stream (useful for error handling)

+There are some niche features of @root/request which are beyond the request.js
+compatibility.
+
+## async/await & Promises
+
+The differences in async support are explained in [README.md](/README.md), up near the top.
+
+If you're familiar with Promises (and async/await), then it's pretty self-explanatory.
+
+## ok
+
+Just like WHATWG `fetch`, we have `resp.ok`:
+
+```js
+let resp = await request({
+    url: 'https://example.com'
+}).then(mustOk);
+```
+
+```js
+function mustOk(resp) {
+    if (!resp.ok) {
+        // handle error
+        throw new Error('BAD RESPONSE');
+    }
+    return resp;
+}
+```
+
+## streams
+
+The differences in stream support are explained in [README.md](/README.md), up near the top.
+
+## userAgent
+
+There's a default User-Agent string describing the version of @root/request, node.js, and the OS.
+
+Add to the default User-Agent
+
+```js
+request({
+    // ...
+    userAgent: 'my-package/1.0' // add to agent
+});
+```
+
+Replace the default User-Agent
+
+```js
+request({
+    // ...
+    headers: { 'User-Agent': 'replace/0.0' }
+});
+```
+
+Disable the default User-Agent:
+
+```js
+request({
+    // ...
+    headers: { 'User-Agent': false }
+});
+```

+**Streaming**
+
+In order to keep this library lightweight, performant, and keep the code easy to
+read, the streaming behavior is **_slightly different_** from that of
+`request.js`.
+
+```diff
+-var request = require('request');
++var request = require('@root/request');
+
+-var stream = request({ url, headers });
++var stream = await request({ url, headers });
+
+ let attachment = await new MailgunAPI.Attachment({
+   data: stream
+ })
+```
+
+Example:
+
+```js
+var request = require('@root/request');
+
+var resp = await request({
+    url: 'http://www.google.com',
+    stream: true // true | 'filename.ext' | stream.Writable
+});
+
+// 'resp' itself is a ReadableStream
+resp.on('data', function () {
+    // got some data
+});
+
+resp.on('end', function () {
+    // the data has ended
+});
+
+// 'resp.stream' is a Promise that is resolved when the read stream is destroyed
+await resp.stream; // returns `undefined`
+console.log('Done');
+```
+
+The difference is that we don't add an extra layer of stream abstraction.
+You must use the response from await, a Promise, or the callback.
+
+You can also give a file path:
+
+```js
+request({
+    url: 'http://www.google.com',
+    stream: '/tmp/google-index.html'
+});
+```
+
+Which is equivalent to passing a write stream for the file:
+
+```js
+request({
+    url: 'http://www.google.com',
+    stream: fs.createWriteStream('/tmp/google-index.html')
+});
+```
+
+Also, `await resp.stream.body()` can be used to get back the full body (the same as if you didn't use the `stream` option:
+
+```js
+let resp = await request({
+    url: 'http://www.google.com',
+    stream: true
+});
+if (!resp.ok) {
+    await resp.stream.body();
+    console.error(resp.body);
+}
+```
