 KubeVela practices the "render, orchestrate, deploy" workflow with below highlighted values added to existing ecosystem:
 
-* Deployment as Code
+#### **Deployment as Code**
 
-Declare your deployment plan as workflow, run it automatically with any CI/CD or GitOps system, extend or re-program the workflow steps with CUE. No ad-hoc scripts, no dirty glue code, just deploy. The deployment workflow in KubeVela is powered by [Open Application Model](https://oam.dev/).

+#### **Built-in observability, multi-tenancy and security support**
 
-Choose from the wide range of LDAP integrations we provided out-of-box, enjoy multi-cluster authorization that is fully automated, pick and apply fine-grained RBAC modules and customize them per your own supply chain requirements.
+Choose from the wide range of LDAP integrations we provided out-of-box, enjoy enhanced [multi-tenancy and multi-cluster authorization and authentication](https://kubevela.net/docs/platform-engineers/auth/advance),
+pick and apply fine-grained RBAC modules and customize them per your own supply chain requirements.
+All delivery process has fully [automated observability dashboards](https://kubevela.net/docs/platform-engineers/operations/observability).

+Natively supports multi-cluster/hybrid-cloud scenarios such as progressive rollout across test/staging/production environments,
+automatic canary, blue-green and continuous verification, rich placement strategy across clusters and clouds,
+along with automated cloud environments provision.
+
+#### **Lightweight but highly extensible architecture**
+
+Minimize your control plane deployment with only one pod and 0.5c1g resources to handle thousands of application delivery.
+Glue and orchestrate all your infrastructure capabilities as reusable modules with a highly extensible architecture
+and share the large growing community [addons](https://kubevela.net/docs/reference/addons/overview).
