+
+## Reproduce
+
+This is a mirror of the kgateway [inference conformance GHA workflow](https://github.com/kgateway-dev/kgateway/blob/v2.0.x/.github/actions/kube-inference-extension-conformance-tests/action.yaml).
+
+### Prerequisites
+
+In order to run the conformance tests, the following prerequisites must be met:
+
+- The [kubectl](https://kubernetes.io/docs/tasks/tools/) command-line tool installed and configured for the active cluster context.
+- The [helm](https://github.com/helm/helm), [git](https://git-scm.com/downloads), and [make](https://www.gnu.org/software/make/) command-line tools installed.
+
+### Steps
+
+1. Set the environment variables use by the proceeding steps:
+
+   ```sh
+   # The kgateway version
+   export VERSION=v2.0.4
+   # Skip building and loading the kgateway images
+   export SKIP_DOCKER=true
+   # Install Gateway API and Inference Extension CRDs
+   export CONFORMANCE=true
+   ```
+
+2. Clone the kgateway repository and checkout the release:
+
+   ```sh
+   git clone -b $VERSION https://github.com/kgateway-dev/kgateway.git && cd kgateway
+   ```
+
+3. Create a KinD cluster:
+
+   ```sh
+   make kind-setup
+   ```
+
+4. Install the kgateway CRDs:
+
+   ```sh
+   helm upgrade -i --create-namespace --namespace kgateway-system \
+   --version $VERSION kgateway-crds oci://cr.kgateway.dev/kgateway-dev/charts/kgateway-crds
+   ```
+
+5. Install kgateway with Inference Extension enabled:
+
+   ```sh
+   helm upgrade -i --namespace kgateway-system --version $VERSION \
+   kgateway oci://cr.kgateway.dev/kgateway-dev/charts/kgateway --set inferenceExtension.enabled=true
+   ```
+
+6. Wait for the kgateway rollout to complete:
+
+   ```sh
+   kubectl rollout status deploy/kgateway -n kgateway-system
+   ```
+
+7. Run the conformance tests:
+
+   ```sh
+   make gie-conformance
+   ```
+
+8. View and verify the conformance report:
+
+   ```sh
+   cat _test/conformance/inference-$VERSION-report.yaml
+   ```
