-  This code is currently only intended to be used by ostree
-  to fetch content via containers.  The API is subject
-  to change.  A goal however is to stabilize the API
-  eventually as a full out-of-process interface to the
-  core containers/image library functionality.
-
-  To use this command, in a parent process create a
-  `socketpair()` of type `SOCK_SEQPACKET`.  Fork
-  off this command, and pass one half of the socket
-  pair to the child.  Providing it on stdin (fd 0)
-  is the expected default.
-
-  The protocol is JSON for the control layer,
-  and  a read side of a `pipe()` passed for large data.
-
- Base JSON protocol:
-
- request: { method: "MethodName": args: [arguments] }
- reply: { success: bool, value: JSVAL, pipeid: number, error: string }
-
- For any non-metadata i.e. payload data from `GetManifest`
- and `GetBlob` the server will pass back the read half of a `pipe(2)` via FD passing,
- along with a `pipeid` integer.
-
- The expected flow looks like this:
-
-  - Initialize
-    And validate the returned protocol version versus
-	what your client supports.
-  - OpenImage docker://quay.io/someorg/example:latest
-    (returns an imageid)
-  - GetManifest imageid (and associated <pipeid>)
-  (Streaming read data from pipe)
-  - FinishPipe <pipeid>
-  - GetBlob imageid sha256:...
-  (Streaming read data from pipe)
-  - FinishPipe <pipeid>
-  - GetBlob imageid sha256:...
-  (Streaming read data from pipe)
-  - FinishPipe <pipeid>
-  - CloseImage imageid
-
- You may interleave invocations of these methods, e.g. one
- can also invoke `OpenImage` multiple times, as well as
- starting multiple GetBlob requests before calling `FinishPipe`
- on them.  The server will stream data into the pipefd
- until `FinishPipe` is invoked.
-
- Note that the pipe will not be closed by the server until
- the client has invoked `FinishPipe`.  This is to ensure
- that the client checks for errors.  For example, `GetBlob`
- performs digest (e.g. sha256) verification and this must
- be checked after all data has been written.

-### Building a static binary
-
-There have been efforts in the past to produce and maintain static builds, but the maintainers prefer to run Skopeo using distro packages or within containers. This is because static builds of Skopeo tend to be unreliable and functionally restricted. Specifically:
-- Some features of Skopeo depend on non-Go libraries like `libgpgme` and `libdevmapper`.
-- Generating static Go binaries uses native Go libraries, which don't support e.g. `.local` or LDAP-based name resolution.
-
-That being said, if you would like to build Skopeo statically, you might be able to do it by combining all the following steps.
-- Export environment variable `CGO_ENABLED=0` (disabling CGO causes Go to prefer native libraries when possible, instead of dynamically linking against system libraries).
-- Set the `BUILDTAGS=containers_image_openpgp` Make variable (this remove the dependency on `libgpgme` and its companion libraries).
-- Clear the `GO_DYN_FLAGS` Make variable (which otherwise seems to force the creation of a dynamic executable).
-
-The following command implements these steps to produce a static binary in the `bin` subdirectory of the repository:
-
-```bash
-docker run -v $PWD:/src -w /src -e CGO_ENABLED=0 golang \
-make BUILDTAGS=containers_image_openpgp GO_DYN_FLAGS=
-```
-
-Keep in mind that the resulting binary is unsupported and might crash randomly. Only use if you know what you're doing!

It also contains other helpers and functions for managing Windows Containers such as the Golang interface for the Host Network Service (HNS), as well as code for the [guest agent](./internal/guest/README.md) (commonly referred to as the GCS or Guest Compute Service in the codebase) used to support running Linux Hyper-V containers.
+This package contains the Golang interface for using the Windows [Host Compute Service](https://techcommunity.microsoft.com/t5/containers/introducing-the-host-compute-service-hcs/ba-p/382332) (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](https://github.com/moby/moby) and [Containerd](https://github.com/containerd/containerd) projects, but it can be freely used by other projects as well.
-
-## Building
-
-While this repository can be used as a library of sorts to call the HCS apis, there are a couple binaries built out of the repository as well. The main ones being the Linux guest agent, and an implementation of the [runtime v2 containerd shim api](https://github.com/containerd/containerd/blob/master/runtime/v2/README.md).
-### Linux Hyper-V Container Guest Agent
-
-To build the Linux guest agent itself all that's needed is to set your GOOS to "Linux" and build out of ./cmd/gcs.
-```powershell
-C:\> $env:GOOS="linux"
-C:\> go build .\cmd\gcs\
-```
-
-or on a Linux machine
-```sh
-> go build ./cmd/gcs
-```
-
-If you want it to be packaged inside of a rootfs to boot with alongside all of the other tools then you'll need to provide a rootfs that it can be packaged inside of. An easy way is to export the rootfs of a container.
-
-```sh
-docker pull busybox
-docker run --name base_image_container busybox
-docker export base_image_container | gzip > base.tar.gz
-BASE=./base.tar.gz
-make all
-```
-
-If the build is successful, in the `./out` folder you should see:
-```sh
-> ls ./out/
-delta.tar.gz  initrd.img  rootfs.tar.gz
-```
-
-### Containerd Shim
-For info on the Runtime V2 API: https://github.com/containerd/containerd/blob/master/runtime/v2/README.md.
-
-Contrary to the typical Linux architecture of shim -> runc, the runhcs shim is used both to launch and manage the lifetime of containers.
-
-```powershell
-C:\> $env:GOOS="windows"
-C:\> go build .\cmd\containerd-shim-runhcs-v1
-```
-
-Then place the binary in the same directory that Containerd is located at in your environment. A default Containerd configuration file can be generated by running:
-```powershell
-.\containerd.exe config default | Out-File "C:\Program Files\containerd\config.toml" -Encoding ascii
-```
-
-This config file will already have the shim set as the default runtime for cri interactions.
-
-To trial using the shim out with ctr.exe:
-```powershell
-C:\> ctr.exe run --runtime io.containerd.runhcs.v1 --rm mcr.microsoft.com/windows/nanoserver:2004 windows-test cmd /c "echo Hello World!"
-```
+It is primarily used in the [Moby Project](https://github.com/moby/moby), but it can be freely used by other projects as well.

-Because of this, for most code changes you may need to run `go mod vendor` + `go mod tidy` in the /test directory in this repository, as the
-CI in this project will check if the files are out of date and will fail if this is true.
+We also ask that contributors [sign their commits](https://git-scm.com/docs/git-commit) using `git commit -s` or `git commit --signoff` to certify they either authored the work themselves or otherwise have permission to use it in this project.
