 ## Enabling a namespace to run Function related Tekton Pipelines
-1. Add permission to deploy on Knative to `default` Service Account: (This is not needed on OpenShift)
+
+Set up RBAC permissions for the `default` Service Account to deploy Functions: (This is not needed on OpenShift). 
+Depending on the to be used deployers, different permissions are required: 
+
+### Option A: Permissions for all deployers (knative, raw and Keda)
+
+If you plan to use all deployers, you need the full set of permissions.
+
+```bash
+export NAMESPACE=<INSERT_YOUR_NAMESPACE>
+
+kubectl create role func-deployer \
+  --verb=get,list,create,update,delete \
+  --resource=deployments.apps,replicasets.apps,pods,services,httpscaledobjects.http.keda.sh \
+  --namespace=$NAMESPACE
+
+kubectl create rolebinding func-deployer-binding \
+  --role=func-deployer \
+  --serviceaccount=$NAMESPACE:default \
+  --namespace=$NAMESPACE
+  
+kubectl create clusterrolebinding $NAMESPACE:knative-eventing-namespaced-admin \
+  --clusterrole=knative-eventing-namespaced-admin \
+  --serviceaccount=$NAMESPACE:default
+  
+kubectl create clusterrolebinding $NAMESPACE:knative-serving-namespaced-admin \
+  --clusterrole=knative-serving-namespaced-admin \
+  --serviceaccount=$NAMESPACE:default
+```
+
+### Option B: Permissions only needed for the raw Deployer
+```bash
+export NAMESPACE=<INSERT_YOUR_NAMESPACE>
+
+kubectl create clusterrolebinding $NAMESPACE:knative-eventing-namespaced-admin \
+  --clusterrole=knative-eventing-namespaced-admin \
+  --serviceaccount=$NAMESPACE:default

+  --namespace=$NAMESPACE
+
+kubectl create rolebinding func-deployer-binding \
+  --role=func-deployer \
+  --serviceaccount=$NAMESPACE:default \
+  --namespace=$NAMESPACE
+```
+
+### Option C: Permissions only needed for the KEDA Deployer
+
+Same as for the raw deployer, but additionally permissions for the `HTTPScaledObjects`:
+
+```bash
+export NAMESPACE=<INSERT_YOUR_NAMESPACE>
+
+kubectl create clusterrolebinding $NAMESPACE:knative-eventing-namespaced-admin \
+  --clusterrole=knative-eventing-namespaced-admin \
+  --serviceaccount=$NAMESPACE:default

+kubectl create role func-deployer \
+  --verb=get,list,create,update,delete \
+  --resource=deployments.apps,replicasets.apps,pods,services,httpscaledobjects.http.keda.sh \
+  --namespace=$NAMESPACE
+
+kubectl create rolebinding func-deployer-binding \
+  --role=func-deployer \
+  --serviceaccount=$NAMESPACE:default \
+  --namespace=$NAMESPACE
+```
+
+### Option D: Permissions only needed for the Knative Deployer
 ```bash
 export NAMESPACE=<INSERT_YOUR_NAMESPACE>
+
+kubectl create clusterrolebinding $NAMESPACE:knative-eventing-namespaced-admin \
+  --clusterrole=knative-eventing-namespaced-admin \
+  --serviceaccount=$NAMESPACE:default

---clusterrole=knative-serving-namespaced-admin  --serviceaccount=$NAMESPACE:default
