+description: """
+[![Build Status (Linux)](https://travis-ci.org/mirage/ocaml-hvsock.svg)](https://travis-ci.org/mirage/ocaml-hvsock)
+[![Build status (Windows)](https://ci.appveyor.com/api/projects/status/974tsg317b4k8xra?svg=true)](https://ci.appveyor.com/project/mirage/ocaml-hvsock/branch/master)
+
+These bindings allow Host <-> VM communication on Hyper-V systems on both Linux
+and Windows.
+
+*Warning*: the `AF_HYPERV` patches for Linux are not yet merged and hence the
+definition of `AF_HYPERV` is not yet stable. If other address families are merged
+before this one then the value of `AF_HYPERV` will change!
+
+Please read [the API documentation](https://djs55.github.io/ocaml-hvsock/index.html)."""
