-Supported impersonate versions, as supported by my [fork](https://github.com/yifeikong/curl-impersonate) of [curl-impersonate](https://github.com/lwthiker/curl-impersonate):
+`curl_cffi` supports the same browser versions as supported by my [fork](https://github.com/yifeikong/curl-impersonate) of [curl-impersonate](https://github.com/lwthiker/curl-impersonate):
 
 However, only Chrome-like browsers are supported. Firefox support is tracked in [#59](https://github.com/yifeikong/curl_cffi/issues/59).
 
 Browser versions will be added **only** when their fingerprints change. If you see a version, e.g.
 chrome122, were skipped, you can simply impersonate it with your own headers and the previous version.
 
+If you are trying to impersonate a target other than a browser, use `ja3=...` and `akamai=...`
+to specify your own customized fingerprints.
