+## How do I implement NTLM authentication?
+
+Microsoft is phasing out NTLM. For this reason, NTLM authentication won't be implemented in this library. However, it should be possible with the following curl options:

+- `CURLOPT_USERPWD` with username and password, for example "username:password"
+
+Check [examples.md](examples.md) for an example.
