+## Azure Pipelines
+
+Use the reusable `setup-vp` step template in your Azure Pipelines configuration. Create a GitHub service connection named `github`, then reference the template from the `setup-vp` repository:
+
+```yaml [azure-pipelines.yml]
+resources:
+  repositories:
+    - repository: setupVp
+      type: github
+      endpoint: github
+      name: voidzero-dev/setup-vp
+      ref: refs/tags/<setup-vp-version>
+
+pool:
+  vmImage: ubuntu-latest
+
+steps:
+  - checkout: self
+  - template: azure/setup-vp.yml@setupVp
+    parameters:
+      setupRef: '<setup-vp-version>'
+      nodeVersion: 24.x
+      cache: true
+      runInstall: true
+  - script: vp check
+  - script: vp test
+  - script: vp build
+```
+
+Pin `ref` and `setupRef` to the same tag or commit SHA for strict reproducibility.
+
+The Azure Pipelines template supports Microsoft-hosted Linux, macOS, and Windows agents. It uses Azure's native `UseNode@1` and `Cache@2` tasks to set up Node.js and cache package-manager data.

 ## Simplifying Existing Workflows
 
 If you are migrating an existing GitHub Actions workflow, you can often replace large blocks of Node, package-manager, and cache setup with a single `setup-vp` step.
