+
+Today, we are happy to share that our first **alpha version of KEDA 2.0 is available**! 🎊
+
+# Highlights
+
+With this release, we are shipping majority of our planned features.
+
+Here are some highlights:
+
+- **Making scaling more powerful**
+    - Introduction of `ScaledJob` ([docs](https://keda.sh/docs/2.0/concepts/scaling-jobs/))
+    - Support for scaling Deployments, Stateful Sets and/or any Custom Resources ([docs](https://keda.sh/docs/2.0/concepts/scaling-deployments/))
+    - Support for scaling on standard resource metrics (CPU/Memory)
+    - Support for multiple triggers in a single `ScaledObject` ([docs](https://keda.sh/docs/2.0/concepts/scaling-deployments/))
+    - Support for scaling to original replica count after deleting `ScaledObject` ([docs](https://keda.sh/docs/2.0/concepts/scaling-deployments/))
+    - Support for controling scaling behavior of underlying HPA
+- **Easier to operate KEDA**
+    - Introduction of readiness and liveness probes
+    - Introduction of Prometheus metrics for Metrics Server ([docs](https://keda.sh/docs/2.0/operate/))
+    - Provide more information when quering KEDA resources with `kubectl`
+- **Extensibility**
+    - Introduction of External Push scaler ([docs](https://keda.sh/docs/2.0/scalers/external-push/))
+    - Provide Go client
+
+For a full list of changes, we highly recommend going through [our changelog](https://github.com/kedacore/keda/blob/v2/CHANGELOG.md#v200)!
+
+# Getting started
+
+TODO but need input, just list Helm? This legit?
+
+>$ helm install keda kedacore/keda --namespace keda --version 2.0.0-alpha
+
+
+# Migrating to KEDA 2.0
+
+We want it to be super simple to use 2.0 as an existing customer! But what has changed?
+
+- API namespace for KEDA Custom Resources Definitions (CRD) has changed from `keda.k8s.io` to `keda.sh`
+- Scaling jobs is now done throught `ScaledJob` CRD, instead of `ScaledObject` CRD
+- `ScaledObject` is now using `spec.scaleTargetRef.name`, instead of `spec.scaleTargetRef.deploymentName`
+- `ScaledObject` no longer requires `deploymentName` label _(last couple of v1 releases were already ignoring it)_
+
+Learn more on how to migrate by using our [migration guide](https://keda.sh/docs/2.0/migration/)!
+
+With our official release we will provide [migration scripts](https://github.com/kedacore/keda/issues/946) allowing you to migrate your KEDA resources automatically.
+
+> **⚠ Running KEDA 1.x & 2.0 Alpha side-by-side is not supported.**
+> 
+> KEDA is comes with a metrics server and Kubernetes only allows you to run one of them in a cluster.
+> 
+>_Learn more about how KEDA is architected in [our docs](http://keda.sh/docs/latest/concepts/#architecture)._
+
+# Conclusion
+
+We are looking forward to hearing your feedback:
+
+- What do you like and/or what could be improved?
+- What issues did you find?
+- How can the migration be smoother?
+
+While we are eagerly waiting for feedback, we plan to release KEDA 2.0 by the end of August, 2020.
+
+Thanks for reading, and happy scaling!
