+== containerd Proposal
+
+*Name of project:* containerd
+
+*Description*
+
+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, and low-level storage, etc..
+
+containerd is designed to be embedded into a larger system, rather than being used directly by developers or end-users. containerd will serve as a core container runtime for the CNCF ecosystem.
