+
+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.
+
+containerd is designed to be embedded into a larger system, rather than being used directly by developers or end-users.
+
+![architecture](design/architecture.png)
+
+## Getting Started
+
+See our documentation on [containerd.io](https://containerd.io):
+* [for ops and admins](docs/ops.md)
+* [namespaces](docs/namespaces.md)
+* [client options](docs/client-opts.md)
+
+See how to build containerd from source at [BUILDING](BUILDING.md).
+
+If you are interested in trying out containerd see our example at [Getting Started](docs/getting-started.md).
+
+
+## Runtime Requirements
+
+Runtime requirements for containerd are very minimal. Most interactions with
+the Linux and Windows container feature sets are handled via [runc](https://github.com/opencontainers/runc) and/or
+OS-specific libraries (e.g. [hcsshim](https://github.com/Microsoft/hcsshim) for Microsoft). The current required version of `runc` is always listed in [RUNC.md](/RUNC.md).
+
+There are specific features
+used by containerd core code and snapshotters that will require a minimum kernel
+version on Linux. With the understood caveat of distro kernel versioning, a
+reasonable starting point for Linux is a minimum 4.x kernel version.
+
+The overlay filesystem snapshotter, used by default, uses features that were
+finalized in the 4.x kernel series. If you choose to use btrfs, there may
+be more flexibility in kernel version (minimum recommended is 3.18), but will
+require the btrfs kernel module and btrfs tools to be installed on your Linux
+distribution.
+
+To use Linux checkpoint and restore features, you will need `criu` installed on
+your system. See more details in [Checkpoint and Restore](#checkpoint-and-restore).
+
+Build requirements for developers are listed in [BUILDING](BUILDING.md).
+
+## Features
+
+### Client
+
+containerd offers a full client package to help you integrate containerd into your platform.
+
+```go
+
+import (
+  "github.com/containerd/containerd"
+  "github.com/containerd/containerd/cio"
+)
+
+
+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"))
+```
+
+### 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
+
+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.
+
+```go
+redis, err := client.NewContainer(context, "redis-master")
+defer redis.Delete(context)
+```
+
+### OCI Runtime Specification
+
+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.
+
+You can specify options when creating a container about how to modify the specification.
+
+```go
+redis, err := client.NewContainer(context, "redis-master", containerd.WithNewSpec(oci.WithImageConfig(image)))
+```
+
+### Root Filesystems
+
+containerd allows you to use overlay or snapshot filesystems with your containers.  It comes with builtin support for overlayfs and btrfs.
+
+```go
+// pull an image and unpack it into the configured snapshotter
+image, err := client.Pull(context, "docker.io/library/redis:latest", containerd.WithPullUnpack)
+
+// 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(oci.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(oci.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, cio.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)
+```
+
+### 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

+
+// Package platforms provides a toolkit for normalizing, matching and
+// specifying container platforms.
+//
+// Centered around OCI platform specifications, we define a string-based
+// specifier syntax that can be used for user input. With a specifier, users
+// only need to specify the parts of the platform that are relevant to their
+// context, providing an operating system or architecture or both.
+//
+// How do I use this package?
+//
+// The vast majority of use cases should simply use the match function with
+// user input. The first step is to parse a specifier into a matcher:
+//
+//   m, err := Parse("linux")
+//   if err != nil { ... }
+//
+// Once you have a matcher, use it to match against the platform declared by a
+// component, typically from an image or runtime. Since extracting an images
+// platform is a little more involved, we'll use an example against the
+// platform default:
+//
+//   if ok := m.Match(Default()); !ok { /* doesn't match */ }
+//
+// This can be composed in loops for resolving runtimes or used as a filter for
+// fetch and select images.
+//
+// More details of the specifier syntax and platform spec follow.
+//
+// Declaring Platform Support
+//
+// Components that have strict platform requirements should use the OCI
+// platform specification to declare their support. Typically, this will be
+// images and runtimes that should make these declaring which platform they
+// support specifically. This looks roughly as follows:
+//
+//   type Platform struct {
+//	   Architecture string
+//	   OS           string
+//	   Variant      string
+//   }
+//
+// Most images and runtimes should at least set Architecture and OS, according
+// to their GOARCH and GOOS values, respectively (follow the OCI image
+// specification when in doubt). ARM should set variant under certain
+// discussions, which are outlined below.
+//
+// Platform Specifiers
+//
+// While the OCI platform specifications provide a tool for components to
+// specify structured information, user input typically doesn't need the full
+// context and much can be inferred. To solve this problem, we introduced
+// "specifiers". A specifier has the format
+// `<os>|<arch>|<os>/<arch>[/<variant>]`.  The user can provide either the
+// operating system or the architecture or both.
+//
+// An example of a common specifier is `linux/amd64`. If the host has a default
+// of runtime that matches this, the user can simply provide the component that
+// matters. For example, if a image provides amd64 and arm64 support, the
+// operating system, `linux` can be inferred, so they only have to provide
+// `arm64` or `amd64`. Similar behavior is implemented for operating systems,
+// where the architecture may be known but a runtime may support images from
+// different operating systems.
+//
+// Normalization
+//
+// Because not all users are familiar with the way the Go runtime represents
+// platforms, several normalizations have been provided to make this package
+// easier to user.
+//
+// The following are performed for architectures:
+//
+//   Value    Normalized
+//   aarch64  arm64
+//   armhf    arm
+//   armel    arm/v6
+//   i386     386
+//   x86_64   amd64
+//   x86-64   amd64
+//
+// We also normalize the operating system `macos` to `darwin`.
+//
+// ARM Support
+//
+// To qualify ARM architecture, the Variant field is used to qualify the arm
+// version. The most common arm version, v7, is represented without the variant
+// unless it is explicitly provided. This is treated as equivalent to armhf. A
+// previous architecture, armel, will be normalized to arm/v6.
+//
+// While these normalizations are provided, their support on arm platforms has
+// not yet been fully implemented and tested.

 1. osxkeychain: Provides a helper to use the OS X keychain as credentials store.
 2. secretservice: Provides a helper to use the D-Bus secret service as credentials store.
 3. wincred: Provides a helper to use Windows credentials manager as store.
+4. pass: Provides a helper to use `pass` as credentials store.

+#### Note
+
+`pass` needs to be configured for `docker-credential-pass` to work properly.
+It must be initialized with a `gpg2` key ID. Make sure your GPG key exists is in `gpg2` keyring as `pass` uses `gpg2` instead of the regular `gpg`.
