+# Grafana Dashboard Configuration
+
+## Updating Datasource UID
+
+The dashboard JSON files in this directory reference datasources using a unique identifier (UID). If you need to update the datasource UID to match your Grafana instance, follow the instructions below.
+
+### Method 1: Grafana UI (Easiest)
+
+1. Navigate to **Grafana** → **Connections** → **Data sources**
+2. Click on the datasource you want to use (e.g., **Prometheus**)
+3. Look at the **URL in your browser's address bar**
+4. The UID will be visible in the URL (typically after `/datasources/edit/`)
+   - Example: `http://localhost:3000/datasources/edit/prometheus` → UID is `prometheus`
+
+### Updating the Dashboard Files
+
+Once you have the UID, you can update it in the dashboard JSON files:
+
+Find sections like this:
+
+```json
+"datasource": {
+  "type": "prometheus",
+  "uid": "prometheus"
+}
+```
+
+Replace the `"uid"` value with the UID you found in step 3 above.
+
+### Note
+
+- The default UID for Prometheus in these dashboards is `prometheus`
+- If your Grafana instance uses a different UID, you'll need to update all dashboard files accordingly
+- You can use a find-and-replace tool to update multiple files at once
