+Downloadable 64-bit Intel/AMD binaries of all official releases are available on
+our [releases page](https://github.com/containerd/containerd/releases), as well as
+auto-published to the [cri-containerd-release storage bucket](https://console.cloud.google.com/storage/browser/cri-containerd-release?pli=1).

+For other architectures and distribution support, you will find that many
+Linux distributions package their own containerd and provide it across several
+architectures, such as [Canonical's Ubuntu packaging](https://launchpad.net/ubuntu/bionic/+package/containerd).
+
+#### Enabling command auto-completion
+
+Starting with containerd 1.4, the urfave client feature for auto-creation of bash and zsh
+autocompletion data is enabled. To use the autocomplete feature in a bash shell for example, source
+the autocomplete/ctr file in your `.bashrc`, or manually like:
+
+```
+$ source ./contrib/autocomplete/ctr
+```
+
+#### Distribution of `ctr` autocomplete for bash and zsh
+
+For bash, copy the `contrib/autocomplete/ctr` script into
+`/etc/bash_completion.d/` and rename it to `ctr`. The `zsh_autocomplete`
+file is also available and can be used similarly for zsh users.
+
+Provide documentation to users to `source` this file into their shell if
+you don't place the autocomplete file in a location where it is automatically
+loaded for the user's shell environment.

-# How to Contribute
-
-## Getting Started
-
-- Fork the repository on GitHub
-- Read the [README](README.markdown) for build and test instructions
-- Play with the project, submit bugs, submit patches!
-
-## Contribution Flow
-
-This is a rough outline of what a contributor's workflow looks like:
-
-- Create a topic branch from where you want to base your work (usually master).
-- Make commits of logical units.
-- Make sure your commit messages are in the proper format (see below).
-- Push your changes to a topic branch in your fork of the repository.
-- Make sure the tests pass, and add any new tests as appropriate.
-- Submit a pull request to the original repository.
-
-Thanks for your contributions!
-
-### Format of the Commit Message
-
-We follow a rough convention for commit messages that is designed to answer two
-questions: what changed and why. The subject line should feature the what and
-the body of the commit should describe the why.
-
-```
-scripts: add the test-cluster command
-
-this uses tmux to setup a test cluster that you can easily kill and
-start for debugging.
-
-Fixes #38
-```
-
-The format can be described more formally as follows:
-
-```
-<subsystem>: <what changed>
-<BLANK LINE>
-<why this change was made>
-<BLANK LINE>
-<footer>
-```
-
-The first line is the subject and should be no longer than 70 characters, the
-second line is always blank, and other lines should be wrapped at 80 characters.
-This allows the message to be easier to read on GitHub as well as in various
-git tools.

+## Roadmap
+
+With the upcoming [Go2 error proposals](https://go.googlesource.com/proposal/+/master/design/go2draft.md) this package is moving into maintenance mode. The roadmap for a 1.0 release is as follows:
+
+- 0.9. Remove pre Go 1.9 and Go 1.10 support, address outstanding pull requests (if possible)
+- 1.0. Final release.
+
 ## Contributing
 
-We welcome pull requests, bug fixes and issue reports. With that said, the bar for adding new symbols to this package is intentionally set high.
+Because of the Go2 errors changes, this package is not accepting proposals for new functionality. With that said, we welcome pull requests, bug fixes and issue reports. 
 
-Before proposing a change, please discuss your change by raising an issue.
