+# kubernetesconfiguration
+
+> see https://aka.ms/autorest
+
+This is the AutoRest configuration file for KubernetesConfiguration.
+
+## Getting Started
+
+To build the SDKs for UpgradeAssessments in KubernetesConfiguration, simply install AutoRest via `npm` (`npm install -g autorest`) and then run:
+
+> `autorest readme.md`
+
+To see additional help and options, run:
+
+> `autorest --help`
+
+For other options on installation see [Installing AutoRest](https://aka.ms/autorest/install) on the AutoRest github page.
+
+---
+
+## Configuration
+
+### Basic Information
+
+These are the global settings for the UpgradeAssessments in KubernetesConfiguration.
+
+``` yaml
+title: UpgradeAssessmentsClient
+description: APIs for cluster upgrade assessment resources under Microsoft.KubernetesConfiguration.
+openapi-type: arm
+tag: package-2026-06-preview
+```
+
+---
+
+### Tag: package-2026-06-preview
+
+These settings apply only when `--tag=package-2026-06-preview` is specified on the command line.
+
+``` yaml $(tag) == 'package-2026-06-preview'
+input-file:
+  - preview/2026-06-15-preview/upgradeAssessments.json
+suppressions:
+  - code: OperationsAPIImplementation
+    from: upgradeAssessments.json
+    reason: Operations API is implemented as a separate service.
