+### `kubectl-apply`
+
+Validates a kubeconfig, installs kubectl, and applies Kubernetes manifest(s) that live inside the repository (the non-Docker, in-repo analog of `ssh-deploy`'s `compose_files`). Pair it with `deploy-restart` when you also want a rollout restart after the apply — or use it alone for resources that don't need a restart (CronJob, Service, Ingress, Secrets, etc.).
+
+```yaml
+jobs:
+  deploy:
+    runs-on: ubuntu-amd64
+    needs: build
+    steps:
+      - uses: https://git.ivanch.me/ivanch/pipeline-actions/kubectl-apply@main
+        with:
+          kube_config: ${{ secrets.KUBE_CONFIG }}
+          manifest: Mindforge.API/deploy/mindforge-api.yaml
+          # or apply several at once:
+          # manifests: deploy/svc.yaml,deploy/deployment.yaml
+          # optional:
+          # namespace: mindforge   # adds -n when set (manifests may also self-declare)
+```

+| Input | Required | Default | Description |
+|---|---|---|---|
+| `kube_config` | ✅ | — | Full kubeconfig YAML (use secrets) |
+| `manifest` | ❌ | _(empty)_ | Single manifest path (relative to repo root) to apply |
+| `manifests` | ❌ | _(empty)_ | Space-/comma-separated list of manifest paths to apply (each gets its own `kubectl apply -f`) |
+| `namespace` | ❌ | _(empty)_ | Adds `-n <ns>` when non-empty; manifests may also declare their own namespace |
+| `kube_version` | ❌ | `stable` | kubectl version (`stable` or e.g. `v1.31.0`) |
+
+> At least one of `manifest` or `manifests` must be set; a missing file fails the step (the manifest must live in the repo).

 ### `ssh-deploy`
 
 SSH into a remote host and run `docker compose pull` + `docker compose up -d --force-recreate` to deploy the latest images. No third-party SSH action — uses native `ssh` and `ssh-keyscan`.
