@@ -11,10 +11,14 @@ This crate exports all underlying platform types, functions, and constants under
 the crate root, so all items are accessible as `libc::foo`. The types and values
 of all the exported APIs match the platform that libc is compiled for.
 
+Windows API bindings are not included in this crate. If you are looking for WinAPI
+bindings, consider using crates like [windows-sys].

 More detailed information about the design of this library can be found in its
 [associated RFC][rfc].
