 ```yaml
-# GitRepository for llm-workflows
+# GitRepository for Gitea repos (daviestechlabs org)
+# Examples: argo, kubeflow, chat-handler, voice-assistant
 apiVersion: source.toolkit.fluxcd.io/v1
 kind: GitRepository
 metadata:
-  name: llm-workflows
+  name: argo-workflows
   namespace: flux-system
 spec:
-  url: ssh://git@github.com/Billy-Davies-2/llm-workflows
+  url: https://git.daviestechlabs.io/daviestechlabs/argo.git
   ref:
     branch: main
-  secretRef:
-    name: github-deploy-key
+  # Public repos don't need secretRef
 ```
