 ## Helm Repository
 
 The Operator deployment process is managed via Helm. The following Kurrent repository must be configured using the command:
 
 ```bash
-helm repo add kurrentdb-operator-repo \
-  'https://packages.kurrent.io/basic/kurrentdb-operator/helm/charts/' \
-  --username $username \
-  --password $password

 Here's what the command does:
 - Sets the namespace of where the Operator will be deployed i.e. `kurrent` (feel free to change this)
 - Creates the namespace (if it already exists, leave out the `--create-namespace` flag)
 - Deploys CRDs (this can be skipped by removing `--set crds.enabled=true`)
+- Configures the Operator license
 - Deploys a new Helm release called `kurrentdb-operator` in the `kurrent` namespace.
