-## How can I try KEDA v2 Release Candidate 2 version?
-Make sure to remove previous KEDA (including CRD) from the cluster. You can use KEDA Helm chart (include `--devel` when listing) or deploy directly this yaml file:
-```bash
-kubectl apply -f https://github.com/kedacore/keda/releases/download/v2.0.0-rc2/keda-2.0.0-rc2.yaml
-```
-To uninstall run:
-```bash
-kubectl delete -f https://github.com/kedacore/keda/releases/download/v2.0.0-rc2/keda-2.0.0-rc2.yaml
-```
