add help wanted, update slack
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 a member of CNCF with ['graduated'](https://landscape.cncf.io/selected=containerd) status.
+
containerd is designed to be embedded into a larger system, rather than being used directly by developers or end-users.

+## Now Recruiting
+
+We are a large inclusive OSS project that is welcoming help of any kind shape or form:
+* Documentation help is needed to make the product easier to consume and extend.
+* We need OSS community outreach / organizing help to get the word out; manage
+and create messaging and educational content; and to help with social media, community forums/groups, and google groups.
+* We are actively inviting new [security advisors](https://github.com/containerd/project/blob/master/GOVERNANCE.md#security-advisors) to join the team.
+* New sub-projects are being created, core and non-core that could use additional development help.
+* Each of the [containerd projects](https://github.com/containerd) has a list of issues currently being worked on or that need help resolving.
+ - If the issue has not already been assigned to someone, or has not made recent progress and you are interested, please inquire.
+ - If you are interested in starting with a smaller / beginner level issue, look for issues with an `exp/beginner` tag, for example [containerd/containerd beginner issues.](https://github.com/containerd/containerd/issues?q=is%3Aissue+is%3Aopen+label%3Aexp%2Fbeginner)
