 ### Before you begin
 
-- Ensure that you have an up-to-date version of the [IBM Cloud CLI](https://cloud.ibm.com/docs/cli?topic=cli-getting-started).
-- Ensure that you have an up-to-date version of the [IBM Cloud Kubernetes service CLI](https://cloud.ibm.com/docs/containers?topic=containers-kubernetes-service-cli).
-- Ensure that you have an up-to-date version of the [IBM Cloud VPC Infrastructure service CLI](https://cloud.ibm.com/docs/vpc?topic=vpc-vpc-reference). Only required if providing additional security groups with the `var.additional_lb_security_group_ids`.
 - Ensure that you have an up-to-date version of the [jq](https://jqlang.github.io/jq).
 - Ensure that you have an up-to-date version of the [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl).
+- Ensure that you have an up-to-date version of the [oc](https://docs.redhat.com/en/documentation/openshift_container_platform/4.11/html/cli_tools/openshift-cli-oc).
+
+By default, the module automatically downloads the required dependencies if they are not already installed. You can disable this behavior by setting `install_dependencies` to `false`. When enabled, the module fetches dependencies from official online binaries. If you prefer to use third-party repositories, you can specify their URLs by setting the following environment variables: `CUSTOM_KUBECTL_URL`, `CUSTOM_JQ_URL`, and `CUSTOM_OC_URL`.
