+%description
+Microshift is a research project that is exploring how OpenShift Kubernetes
+can be optimized for small form factor and edge computing.
+
+Edge devices deployed out in the field pose very different operational,
+environmental, and business challenges from those of cloud computing.
+These motivate different engineering
+trade-offs for Kubernetes at the far edge than for cloud or near-edge
+scenarios. Microshift's design goals cater to this:
+
+make frugal use of system resources (CPU, memory, network, storage, etc.),
+tolerate severe networking constraints, update (resp. roll back) securely,
+safely, speedily, and seamlessly (without disrupting workloads), and build on
+and integrate cleanly with edge-optimized OSes like Fedora IoT and RHEL for Edge,
+while providing a consistent development and management experience with standard
+OpenShift.
+
+We believe these properties should also make Microshift a great tool for other
+use cases such as Kubernetes applications development on resource-constrained
+systems, scale testing, and provisioning of lightweight Kubernetes control planes.
+
+Note: Microshift is still early days and moving fast. Features are missing.
+Things break. But you can still help shape it, too.
