+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!"
+```

+### Test Directory (Important to note)
+
+This project has tried to trim some dependencies from the root Go modules file that would be cumbersome to get transitively included if this
+project is being vendored/used as a library. Some of these dependencies were only being used for tests, so the /test directory in this project also has
+its own go.mod file where these are now included to get around this issue. Our tests rely on the code in this project to run, so the test Go modules file
+has a relative path replace directive to pull in the latest hcsshim code that the tests actually touch from this project
+(which is the repo itself on your disk).
+
+```
+replace (
+	github.com/Microsoft/hcsshim => ../
+)
+```
+
+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.

+// Package cmp determines equality of values.
+//
+// This package is intended to be a more powerful and safer alternative to
+// reflect.DeepEqual for comparing whether two values are semantically equal.
+// It is intended to only be used in tests, as performance is not a goal and
+// it may panic if it cannot compare the values. Its propensity towards
+// panicking means that its unsuitable for production environments where a
+// spurious panic may be fatal.
+//
+// The primary features of cmp are:
+//
+//   - When the default behavior of equality does not suit the test's needs,
+//     custom equality functions can override the equality operation.
+//     For example, an equality function may report floats as equal so long as
+//     they are within some tolerance of each other.
+//
+//   - Types with an Equal method may use that method to determine equality.
+//     This allows package authors to determine the equality operation
+//     for the types that they define.
+//
+//   - If no custom equality functions are used and no Equal method is defined,
+//     equality is determined by recursively comparing the primitive kinds on
+//     both values, much like reflect.DeepEqual. Unlike reflect.DeepEqual,
+//     unexported fields are not compared by default; they result in panics
+//     unless suppressed by using an Ignore option (see cmpopts.IgnoreUnexported)
+//     or explicitly compared using the Exporter option.

+// Equal reports whether x and y are equal by recursively applying the
+// following rules in the given order to x and y and all of their sub-values:
+//
+//   - Let S be the set of all Ignore, Transformer, and Comparer options that
+//     remain after applying all path filters, value filters, and type filters.
+//     If at least one Ignore exists in S, then the comparison is ignored.
+//     If the number of Transformer and Comparer options in S is non-zero,
+//     then Equal panics because it is ambiguous which option to use.
+//     If S contains a single Transformer, then use that to transform
+//     the current values and recursively call Equal on the output values.
+//     If S contains a single Comparer, then use that to compare the current values.
+//     Otherwise, evaluation proceeds to the next rule.
+//
+//   - If the values have an Equal method of the form "(T) Equal(T) bool" or
+//     "(T) Equal(I) bool" where T is assignable to I, then use the result of
+//     x.Equal(y) even if x or y is nil. Otherwise, no such method exists and
+//     evaluation proceeds to the next rule.
+//
+//   - Lastly, try to compare x and y based on their basic kinds.
+//     Simple kinds like booleans, integers, floats, complex numbers, strings,
+//     and channels are compared using the equivalent of the == operator in Go.
+//     Functions are only equal if they are both nil, otherwise they are unequal.
+//
+// Structs are equal if recursively calling Equal on all fields report equal.
+// If a struct contains unexported fields, Equal panics unless an Ignore option
+// (e.g., cmpopts.IgnoreUnexported) ignores that field or the Exporter option
+// explicitly permits comparing the unexported field.
+//
+// Slices are equal if they are both nil or both non-nil, where recursively
+// calling Equal on all non-ignored slice or array elements report equal.
+// Empty non-nil slices and nil slices are not equal; to equate empty slices,
+// consider using cmpopts.EquateEmpty.

+// Maps are equal if they are both nil or both non-nil, where recursively

+// To use custom comparisons for map keys, consider using cmpopts.SortMaps.
+// Empty non-nil maps and nil maps are not equal; to equate empty maps,
+// consider using cmpopts.EquateEmpty.
