+WebDAV is a well-known, stable and highly flexible protocol for interacting with remote filesystems via an API. Being that it is so widespread, many file hosting services such as **Nextcloud**/**ownCloud**, **Box** and **Yandex** use it as a fallback to their primary interfaces.
 
 This library provides a **WebDAV client** interface that makes interacting with WebDAV enabled services easy. The API returns promises and resolve with the results. It parses and prepares directory-contents requests for easy consumption, as well as providing methods for fetching things like file stats and quotas.

+#### Requests
+
+This library uses [`cross-fetch`](https://github.com/lquixada/cross-fetch) to make requests in a cross-platform manner. It uses the browser's native `fetch` if present, or a polyfill if not. In Node and other environments it uses [`node-fetch`](https://github.com/node-fetch/node-fetch).

+Versions before v5 used Axios for requests.
