-# NetworkPolicy Assistant (derived from Cyclonus)
+# Cyclonus
 
-(Work in Progress)
+## Network policy explainer, prober, and test case generator
 
-Explains your configuration of (Baseline)AdminNetworkPolicy and v1 NetworkPolicy. Additionally, can test conformance of (B)ANP and v1 NetworkPolicy via a connectivity matrix. Derived from the great work of @mattfenwick et al. in [Cyclonus](https://github.com/mattfenwick/cyclonus).
+Parse, explain, and probe network policies to understand their implications and help design
+policies that suit your needs!
 
-TODO: update README once [#150](https://github.com/kubernetes-sigs/network-policy-api/issues/150) is complete.
+## Quickstart
 
-More details here: [Cyclonus](https://github.com/mattfenwick/cyclonus).
+Users: check out our [Quickstart guide](./docs/quickstart.md)
+
+Developers: check out our [Developer guide](./docs/developer-guide.md)
+
+Cyclonus functionality:
+
+ - [run a single network policy test on a cluster](./docs/probe.md)
+ - [run network policy conformance tests on a cluster](./docs/generator.md)
+ - [understand test runs](./docs/test-runs.md)
+ - [analyze network policies](./docs/analyze.md)
+
+
+## Integrations
+
+Cyclonus is available as a [**krew/kubectl plugin**](https://github.com/mattfenwick/kubectl-cyclonus):
+
+ - [Set up krew](https://krew.sigs.k8s.io/docs/user-guide/quickstart/)
+ - install: `kubectl krew install cyclonus`
+ - use: `kubectl cyclonus -h`
+
+**Antrea testing**: [Cyclonus runs network policy tests for Antrea on a daily basis](https://github.com/vmware-tanzu/antrea/actions/workflows/netpol_cyclonus.yml).
+
+**Cilium testing**: [Cyclonus runs network policy tests for Cilium on a daily basis](https://github.com/cilium/cilium/pull/14889).
+
+**Sonobuoy plugin**: [run Cyclonus tests through Sonobuoy](./hack/sonobuoy).
+
+
+## Motivation and History
+
+Testing network policies for CNI providers on Kubernetes has historically been very difficult, requiring a lot of boiler plate.
+This was recently improved upstream via truth table based tests 
+([see KEP](https://github.com/kubernetes/enhancements/tree/master/keps/sig-network/1611-network-policy-validation)).
+Cyclonus is the next evolution of the truth table tests which are part of upstream Kubernetes.
+Cyclonus generates hundreds of network policies, their connectivity tables, and outputs results in the same, easy to read format.
