+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+# cgroups
+
+[![Build Status](https://travis-ci.org/containerd/cgroups.svg?branch=master)](https://travis-ci.org/containerd/cgroups)
+
+[![codecov](https://codecov.io/gh/containerd/cgroups/branch/master/graph/badge.svg)](https://codecov.io/gh/containerd/cgroups)
+
+Go package for creating, managing, inspecting, and destroying cgroups.
+The resources format for settings on the cgroup uses the OCI runtime-spec found
+[here](https://github.com/opencontainers/runtime-spec).
+
+## Examples
+
+### Create a new cgroup
+
+This creates a new cgroup using a static path for all subsystems under `/test`.
+
+* /sys/fs/cgroup/cpu/test
+* /sys/fs/cgroup/memory/test
+* etc....
+
+It uses a single hierarchy and specifies cpu shares as a resource constraint and
+uses the v1 implementation of cgroups.
+
+
+```go
+shares := uint64(100)
+control, err := cgroups.New(cgroups.V1, cgroups.StaticPath("/test"), &specs.LinuxResources{
+    CPU: &specs.CPU{
+        Shares: &shares,
+    },
+})
+defer control.Delete()
+```
+
+### Create with systemd slice support
+
+
+```go
+control, err := cgroups.New(cgroups.Systemd, cgroups.Slice("system.slice", "runc-test"), &specs.LinuxResources{
+    CPU: &specs.CPU{
+        Shares: &shares,
+    },
+})
+
+```
+
+### Load an existing cgroup
+
+```go
+control, err = cgroups.Load(cgroups.V1, cgroups.StaticPath("/test"))
+```
+
+### Add a process to the cgroup
+
+```go
+if err := control.Add(cgroups.Process{Pid:1234}); err != nil {
+}
+```
+
+###  Update the cgroup 
+
+To update the resources applied in the cgroup
+
+```go
+shares = uint64(200)
+if err := control.Update(&specs.LinuxResources{
+    CPU: &specs.CPU{
+        Shares: &shares,
+    },
+}); err != nil {
+}
+```
+
+### Freeze and Thaw the cgroup
+
+```go
+if err := control.Freeze(); err != nil {
+}
+if err := control.Thaw(); err != nil {
+}
+```
+
+### List all processes in the cgroup or recursively
+
+```go
+processes, err := control.Processes(cgroups.Devices, recursive)
+```
+
+### Get Stats on the cgroup
+
+```go
+stats, err := control.Stat()
+```
+
+By adding `cgroups.IgnoreNotExist` all non-existent files will be ignored, e.g. swap memory stats without swap enabled
+```go
+stats, err := control.Stat(cgroups.IgnoreNotExist)
+```
+
+### Move process across cgroups
+
+This allows you to take processes from one cgroup and move them to another.
+
+```go
+err := control.MoveTo(destination)
+```
+
+### Create subcgroup
+
+```go
+subCgroup, err := control.New("child", resources)
+```

-containerd is a daemon to control runC, built for performance and density. 
-containerd leverages runC's advanced features such as seccomp and user namespace support as well
-as checkpoint and restore for cloning and live migration of containers.
+[![GoDoc](https://godoc.org/github.com/containerd/containerd?status.svg)](https://godoc.org/github.com/containerd/containerd)
+[![Build Status](https://travis-ci.org/containerd/containerd.svg?branch=master)](https://travis-ci.org/containerd/containerd)
+[![FOSSA Status](https://app.fossa.io/api/projects/git%2Bhttps%3A%2F%2Fgithub.com%2Fcontainerd%2Fcontainerd.svg?type=shield)](https://app.fossa.io/projects/git%2Bhttps%3A%2F%2Fgithub.com%2Fcontainerd%2Fcontainerd?ref=badge_shield)
+[![Go Report Card](https://goreportcard.com/badge/github.com/containerd/containerd)](https://goreportcard.com/report/github.com/containerd/containerd)
 
-## Getting started
+containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc.
 
-The easiest way to start using containerd is to download binaries from the [releases page](https://github.com/containerd/containerd/releases).
+containerd is designed to be embedded into a larger system, rather than being used directly by developers or end-users.
 
-The included `ctr` command-line tool allows you interact with the containerd daemon:
+![architecture](design/architecture.png)
 
+## Getting Started
+
+If you are interested in trying out containerd please see our [Getting Started Guide](docs/getting-started.md).
+
+## Features
+
+### Client
+
+containerd offers a full client package to help you integrate containerd into your platform.
+
+```go
+
+import "github.com/containerd/containerd"
+
+func main() {
+	client, err := containerd.New("/run/containerd/containerd.sock")
+	defer client.Close()
+}
+
+```
+
+### Namespaces
+
+Namespaces allow multiple consumers to use the same containerd without conflicting with each other.  It has the benefit of sharing content but still having separation with containers and images.
+
+To set a namespace for requests to the API:
+
+```go
+context    = context.Background()
+// create a context for docker
+docker = namespaces.WithNamespace(context, "docker")
+
+containerd, err := client.NewContainer(docker, "id")
+```
+
+To set a default namespace on the client:
+
+```go
+client, err := containerd.New(address, containerd.WithDefaultNamespace("docker"))
 ```
-$ sudo ctr containers start redis /containers/redis
-$ sudo ctr containers list
-ID                  PATH                STATUS              PROCESSES
-redis               /containers/redis   running             14063
+
+### Distribution
+
+```go
+// pull an image
+image, err := client.Pull(context, "docker.io/library/redis:latest")
+
+// push an image
+err := client.Push(context, "docker.io/library/redis:latest", image.Target())
 ```
 
-`/containers/redis` is the path to an OCI bundle. [See the docs for more information.](docs/bundle.md)
+### Containers
+
+In containerd, a container is a metadata object.  Resources such as an OCI runtime specification, image, root filesystem, and other metadata can be attached to a container.
 
-## Docs
+```go
+redis, err := client.NewContainer(context, "redis-master")
+defer redis.Delete(context)
+```
 
- * [Client CLI reference (`ctr`)](docs/cli.md)
- * [Daemon CLI reference (`containerd`)](docs/daemon.md)
- * [Creating OCI bundles](docs/bundle.md)
- * [containerd changes to the bundle](docs/bundle-changes.md)
- * [Attaching to STDIO or TTY](docs/attach.md)
- * [Telemetry and metrics](docs/telemetry.md)
+### OCI Runtime Specification
 
-All documentation is contained in the `/docs` directory in this repository.
+containerd fully supports the OCI runtime specification for running containers.  We have built in functions to help you generate runtime specifications based on images as well as custom parameters.
 
-## Building
+You can specify options when creating a container about how to modify the specification.
 
-You will need to make sure that you have Go installed on your system and the containerd repository is cloned
-in your `$GOPATH`.  You will also need to make sure that you have all the dependencies cloned as well.
-Currently, contributing to containerd is not for the first time devs as many dependencies are not vendored and 
-work is being completed at a high rate.  
+```go
+redis, err := client.NewContainer(context, "redis-master", containerd.WithNewSpec(containerd.WithImageConfig(image)))
+```
 
-After that just run `make` and the binaries for the daemon and client will be localed in the `bin/` directory.
+### Root Filesystems
 
-## Performance
+containerd allows you to use overlay or snapshot filesystems with your containers.  It comes with builtin support for overlayfs and btrfs.
 
-Starting 1000 containers concurrently runs at 126-140 containers per second.
+```go
+// pull an image and unpack it into the configured snapshotter
+image, err := client.Pull(context, "docker.io/library/redis:latest", containerd.WithPullUnpack)
 
-Overall start times:
+// allocate a new RW root filesystem for a container based on the image
+redis, err := client.NewContainer(context, "redis-master",
+	containerd.WithNewSnapshot("redis-rootfs", image),
+	containerd.WithNewSpec(containerd.WithImageConfig(image)),
 
+)
+
+// use a readonly filesystem with multiple containers
+for i := 0; i < 10; i++ {
+	id := fmt.Sprintf("id-%s", i)
+	container, err := client.NewContainer(ctx, id,
+		containerd.WithNewSnapshotView(id, image),
+		containerd.WithNewSpec(containerd.WithImageConfig(image)),
+	)
+}
 ```

+
+### Tasks
+
+Taking a container object and turning it into a runnable process on a system is done by creating a new `Task` from the container.  A task represents the runnable object within containerd.
+
+```go
+// create a new task
+task, err := redis.NewTask(context, containerd.Stdio)
+defer task.Delete(context)
+
+// the task is now running and has a pid that can be use to setup networking
+// or other runtime settings outside of containerd
+pid := task.Pid()
+
+// start the redis-server process inside the container
+err := task.Start(context)
+
+// wait for the task to exit and get the exit status
+status, err := task.Wait(context)
 ```
 
-## Roadmap
+### Checkpoint and Restore
+
+If you have [criu](https://criu.org/Main_Page) installed on your machine you can checkpoint and restore containers and their tasks.  This allow you to clone and/or live migrate containers to other machines.
+
+```go
+// checkpoint the task then push it to a registry
+checkpoint, err := task.Checkpoint(context, containerd.WithExit)
+
+err := client.Push(context, "myregistry/checkpoints/redis:master", checkpoint)
+
+// on a new machine pull the checkpoint and restore the redis container
+image, err := client.Pull(context, "myregistry/checkpoints/redis:master")
+
+checkpoint := image.Target()
+
+redis, err = client.NewContainer(context, "redis-master", containerd.WithCheckpoint(checkpoint, "redis-rootfs"))
+defer container.Delete(context)
+
+task, err = redis.NewTask(context, containerd.Stdio, containerd.WithTaskCheckpoint(checkpoint))
+defer task.Delete(context)
+
+err := task.Start(context)
+```
+
+## Developer Quick-Start
+
+To build the daemon and `ctr` simple test client, the following build system dependencies are required:
+
+* Go 1.9.x or above
+* Protoc 3.x compiler and headers (download at the [Google protobuf releases page](https://github.com/google/protobuf/releases))
+* Btrfs headers and libraries for your distribution. Note that building the btrfs driver can be disabled via build tag removing this dependency.
+
+For proper results, install the `protoc` release into `/usr/local` on your build system. For example, the following commands will download and install the 3.1.0 release for a 64-bit Linux host:
+
+```
+$ wget -c https://github.com/google/protobuf/releases/download/v3.1.0/protoc-3.1.0-linux-x86_64.zip
+$ sudo unzip protoc-3.1.0-linux-x86_64.zip -d /usr/local
+```
+
+With the required dependencies installed, the `Makefile` target named **binaries** will compile the `ctr` and `containerd` binaries and place them in the `bin/` directory. Using `sudo make install` will place the binaries in `/usr/local/bin`. When making any changes to the gRPC API, `make generate` will use the installed `protoc` compiler to regenerate the API generated code packages.
+
+> *Note*: A build tag is currently available to disable building the btrfs snapshot driver.
+> Adding `BUILDTAGS=no_btrfs` to your environment before calling the **binaries**
+> Makefile target will disable the btrfs driver within the containerd Go build.
+
+Vendoring of external imports uses the [`vndr` tool](https://github.com/LK4D4/vndr) which uses a simple config file, `vendor.conf`, to provide the URL and version or hash details for each vendored import. After modifying `vendor.conf` run the `vndr` tool to update the `vendor/` directory contents. Combining the `vendor.conf` update with the changeset in `vendor/` after running `vndr` should become a single commit for a PR which relies on vendored updates.
+
+Please refer to [RUNC.md](/RUNC.md) for the currently supported version of `runc` that is used by containerd.
+
+### Releases and API Stability

+This directory contains the GRPC API definitions for containerd.

+All defined services and messages have been aggregated into `*.pb.txt`

+
+At release time, the current `next.pb.txt` file will be moved into place to
