 The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere.
 
+### Basic docker architecture
+
+This info is from [here](https://stackoverflow.com/questions/41645665/how-containerd-compares-to-runc).
+
+* [containerd](http://containerd.io/) is a container runtime which can m**anage a complete container lifecycle - from image transfer/storage to container execution**, supervision and networking. **More information about containerd below.**
+* container-shim handle headless containers, meaning once runc initializes the containers, it exits handing the containers over to the container-shim which acts as some middleman.
+* [runc](http://runc.io/) is lightweight universal run time container, which abides by the OCI specification. **runc is used by containerd for spawning and running containers according to OCI spec**. It is also the repackaging of libcontainer.
+* [grpc](http://www.grpc.io/) used for communication between containerd and docker-engine.
+* [OCI](https://www.opencontainers.org/) maintains the OCI specification for runtime and images. The current docker versions support OCI image and runtime specs.
