-# Bootstrap faasd on Digitalocean
-
-1) [Sign up to DigitalOcean](https://www.digitalocean.com/?refcode=2962aa9e56a1&utm_campaign=Referral_Invite&utm_medium=Referral_Program&utm_source=CopyPaste)
-2) [Download Terraform](https://www.terraform.io)
-3) Clone this gist using the URL from the address bar
-4) Run `terraform init`
-5) Run `terraform apply -var="do_token=$(cat $HOME/digitalocean-access-token)"`
-6) View the output for the gateway URL
-
-```
-gateway_url = http://178.128.39.201:8080/
-```
-7) View the output for sensitive data via `terraform output` command
-
-```bash
-terraform output login_cmd
-login_cmd = faas-cli login -g http://178.128.39.201:8080/ -p rvIU49CEcFcHmqxj
-
-terraform output password
-password = rvIU49CEcFcHmqxj
-```
-
-Note that the user-data may take a couple of minutes to come up since it will be pulling in various components and preparing the machine.
-
-A single host with 1GB of RAM will be deployed for you, to remove at a later date simply use `terraform destroy`.
-
-If required, you can remove the VM via `terraform destroy -var="do_token=$(cat $HOME/digitalocean-access-token)"`

+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.

+### 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.

+(build as well as install).
+
+If you want to prepend an additional prefix on actual installation (eg. packaging or chroot install),
+you can pass it via `DESTDIR` variable:
+
+```sh
+sudo make install DESTDIR=/tmp/install-x973234/
+```
+
+The above command installs the `containerd` binary to `/tmp/install-x973234/usr/local/bin/containerd`
+
+The current `DESTDIR` convention is supported since containerd v1.6.
+Older releases was using `DESTDIR` for a different purpose that is similar to `PREFIX`.
+
+
 When making any changes to the gRPC API, you can use the installed `protoc`
 compiler to regenerate the API generated code packages with:
 
-```sudo
+```sh
 make generate
 ```
 
 > *Note*: Several build tags are currently available:
-> * `no_btrfs`: A build tag disables building the btrfs snapshot driver.
 > * `no_cri`: A build tag disables building Kubernetes [CRI](http://blog.kubernetes.io/2016/12/container-runtime-interface-cri-in-kubernetes.html) support into containerd.
 > See [here](https://github.com/containerd/cri-containerd#build-tags) for build tags of CRI plugin.
+> * snapshotters (alphabetical order)
+>   * `no_aufs`: A build tag disables building the aufs snapshot driver.
+>   * `no_btrfs`: A build tag disables building the Btrfs snapshot driver.
 >   * `no_devmapper`: A build tag disables building the device mapper snapshot driver.
+>   * `no_zfs`: A build tag disables building the ZFS snapshot driver.
 >
 > For example, adding `BUILDTAGS=no_btrfs` to your environment before calling the **binaries**
 > Makefile target will disable the btrfs driver within the containerd Go build.
