+# Grafana Dashboard Management
+
+This directory contains JSON definitions for Grafana dashboards deployed with Posit Team Dedicated (PTD).
+
+**Important:** Dashboard provisioning via ConfigMaps is currently only supported for AWS workloads.
+
+Dashboards are deployed as Kubernetes ConfigMaps and automatically loaded into Grafana. The deployment process:
+
+1. JSON files in this directory are read by `pulumi_resources/aws_eks_cluster.py` (method `_create_dashboard_configmaps`)
+2. Each JSON file becomes a ConfigMap in the `grafana` namespace
+3. Grafana's dashboard provisioning sidecar watches these ConfigMaps and loads dashboards automatically
+4. Changes to JSON files trigger ConfigMap updates, which Grafana detects and reloads
+5. The dashboard `uid` is automatically set to match the filename (without `.json` extension) for idempotency
+
+**Important:** The `version` field in dashboard JSON is **not used** for version control since we're deploying via ConfigMap (AWS).
