 ## 🆕 Progress capturing
 
 Axios supports both browser and node environments to capture request upload/download progress.
+The frequency of progress events is forced to be limited to `3` times per second.

+## 🔥 Fetch adapter
+
+Fetch adapter was introduced in `v1.7.0`. By default, it will be used if `xhr` and `http` adapters are not available in the build,
+or not supported by the environment.
+To use it by default, it must be selected explicitly:
+
+```js
+const {data} = axios.get(url, {
+  adapter: 'fetch' // by default ['xhr', 'http', 'fetch']
+})
+```
+
+You can create a separate instance for this:
+
+```js
+const fetchAxios = axios.create({
+  adapter: 'fetch'
+});
+
+const {data} = fetchAxios.get(url);
+```
+
+The adapter supports the same functionality as `xhr` adapter, **including upload and download progress capturing**. 
+Also, it supports additional response types such as `stream` and `formdata` (if supported by the environment).
