 You can use these files to stand up your own on-prem Kubernetes cluster. While this repository was built to be run on Raspberry Pi devices, it should be equally valid anywhere Kubernetes can run.
 
+If you want to implement this for yourself, please follow the [setup document](./SETUP.md) (which is actively being updated).

 ## 🎖️ Features
 
 - App-of-apps: A root Argo CD Application deployment schema which recursively manages child apps
-- Namespace deployments: `argocd`, `cert-manager`, `kube-system`, `logging`, `longhorn-system`, and `monitoring`
+- Namespace deployments: `argocd`, `cert-manager`, `kube-system`, `logging`, `longhorn-system`, `monitoring`, and `applications-eng`
 - Cert-manager: X.509 certificate management for Kubernetes
-- Longhorn: Distributed on-prem file storage
+- Longhorn: Distributed on-prem file storage with multiple storage classes
 - Metal LB: An on-prem native software load balancer
 - Monitoring: Prometheus Operator with Grafana using storage PVC through Longhorn
+- n8n: Workflow automation platform with persistent storage
 - Dashboard UI for:
     - Argo CD: For controlling deployments and rollbacks
     - Grafana: For building dashboards against Prometheus data
     - Longhorn: For controlling the distributed block storage setup
+    - n8n: For creating and managing automated workflows
     - Prometheus: For querying against raw data from pods/nodes/deployment resources
