+### Using Azure Custom or Stack clouds
+
+When using custom Azure clouds, there are two methods to configure velero. For potential APIVersion conflicts between the internal azure go SDK versions and the versions of AzureStack or custom clouds, both `BackupStorageLocation` and `VolumeSnapshotLocation` config support an `apiVersion` parameter to pin requests to a specific APIVersion for service api calls.
+
+#### Option 1: Use Azure ResourceManager endpoint discovery
+
+  ```bash
+  cat << EOF > ./credentials-velero
+  AZURE_CLOUD_NAME=AzureCustomCloud
+  AZURE_RESOURCE_MANAGER_ENDPOINT=<Azure resource manager endpoint. For example, https://management.usgovcloudapi.net>
+  EOF
+  ```
+
+#### Option 2: Use Azure cloud configuration
+
+1. Ensure that a valid [cloud provider configuration](https://cloud-provider-azure.sigs.k8s.io/install/configs/) has been created. If using AKS, this can be mounted from the host path `/etc/kubernetes/azurestackcloud.json`
+2. Ensure that the environment variable `AZURE_ENVIRONMENT_FILEPATH` has been set to the location of the file from step 1
+3. Set the configuration (cloud name **must** be `AzureStackCloud`)
+
+  ```bash
+  cat << EOF > ./credentials-velero
+  AZURE_CLOUD_NAME=AzureStackCloud
+  EOF
+  ```
