Do we need Helm Upgrade page?

Not a separate Helm Upgrade page but will be part of the upgrade page under Installation.

This is a reference page for Helm configuration options. Do we have specific upgrade related options?

The only requirements I see here are:

Kubernetes 1.23.8 and higher

cluster-admin permissions in order to install Radius

#### Deploy to Air-gapped environments

Radius pulls container images for control plane services from the GitHub Container Registry (ghcr.io). In environments with strict security controls or no internet access (air‑gapped), mirror the required images to an internal registry and configure Radius to use that registry.

Example of mirroring images (requires access to both registries):

#### Installing Radius in air-gapped environments

The default Radius installation references container images stored in GitHub Container Registry (ghcr.io). In environments without direct access to ghci.io, the container images must be manually pulled and stored in a local OCI registry. For example, the script below pulls from ghcr.io and pushes the images to an internal OCI registry:

+Then install Radius configured to pull images from your private registry, and supply image pull secrets if authentication is required.

Suggested change

Then install Radius configured to pull images from your private registry, and supply image pull secrets if authentication is required.

```bash

rad install kubernetes \

--set global.imageRegistry=myregistry.azurecr.io \

--set global.imageTag={{ .Chart.AppVersion }} \

--set global.imagePullSecrets[0].name=myregistry-secret

Then use the `global.imageRegistry` and `global.imageTag` installation options when installing Radius.

```bash

rad install kubernetes \

--set global.imageRegistry=<internal-oci-registry-hostname> \

--set global.imageTag=0.53

+```
+
+When using a custom registry, images are pulled directly from <registry>/<image-name>:<tag> format. For example, with myregistry.azurecr.io, the controller image will be pulled from myregistry.azurecr.io/controller:latest.


Suggested change

When using a custom registry, images are pulled directly from <registry>/<image-name>:<tag> format. For example, with myregistry.azurecr.io, the controller image will be pulled from myregistry.azurecr.io/controller:latest.

Replace this with instructions on using --set global.imagePullSecrets[0].name=myregistry-secret. But I don't know why this would be required. I would expect Kubernetes to already be configured for this https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/
