+The plugin requires a secret named `argocd-sync-token` with a key called `jwt.txt` containing the Argo CD token.
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: argocd-sync-token
+data:
+  jwt.txt: <base64 encoded token>
+```
+
+The plugin also assumes the Argo CD API server is accessible on a server at this address: `argocd-server.argocd.svc.cluster.local`.
+
+To change the address, edit the value of the ARGOCD_SERVER environment variable in the configmap.
