# hcsshim
This package supports launching Windows Server containers from Go. It is
primarily used in the [Docker Engine](https://github.com/docker/docker) project,
but it can be freely used by other projects as well.
[![Build status](https://ci.appveyor.com/api/projects/status/nbcw28mnkqml0loa/branch/master?svg=true)](https://ci.appveyor.com/project/WindowsVirtualization/hcsshim/branch/master)
This package contains the Golang interface for using the Windows [Host Compute Service](https://blogs.technet.microsoft.com/virtualization/2017/01/27/introducing-the-host-compute-service-hcs/) (HCS) to launch and manage [Windows Containers](https://docs.microsoft.com/en-us/virtualization/windowscontainers/about/). It also contains other helpers and functions for managing Windows Containers such as the Golang interface for the Host Network Service (HNS).
It is primarily used in the [Moby Project](https://github.com/moby/moby), but it can be freely used by other projects as well.
