-### Installation without scheduler
-
-Keptn installed on Kubernetes cluster running Kubernetes >= 1.26
-does not need scheduler for a proper functionality.
-With introduction
-of [Pod scheduling gates](https://kubernetes.io/blog/2022/12/26/pod-scheduling-readiness-alpha/)
-Keptn can use this feature to substitute the functionality of Keptn scheduler.
-
-As this functionality is still disabled by default, it can be enabled by setting up
-the correct helm values.
-This will lead to a Keptn installation without a scheduler and
-with scheduling gates feature enabled.
-
-Use the following command sequence
-to install Keptn with scheduling gates enabled:
-
-```shell
-helm repo add keptn https://charts.lifecycle.keptn.sh
-helm repo update
-helm upgrade --install keptn keptn/keptn -n keptn-system --set schedulingGatesEnabled=true --create-namespace --wait
-```
-
-> **Note**
-Please be aware that scheduling gates functionality in Kubernetes is enabled by default
-in Kubernetes >= 1.27.
-To use it with Kubernetes 1.26, you need to enable it on your cluster.
