 ### Default `Accept-Encoding` value
 
 The default `Accept-Encoding` value contains all possible compression types. So, the following two examples are same.
 
 ```c++
 res = cli.Get("/resource/foo");
-res = cli.Get("/resource/foo", {{"Accept-Encoding", "gzip, deflate, br"}});
+res = cli.Get("/resource/foo", {{"Accept-Encoding", "br, gzip, deflate, zstd"}});
 ```
 
 If we don't want a response without compression, we have to set `Accept-Encoding` to an empty string. This behavior is similar to curl.
