+  Playbook for the GreenhouseCatalogNotReady Alert
+---
+
+## Alert Description
+
+This alert fires when a Greenhouse catalog has not been ready for more than 15 minutes.
+
+## What does this alert mean?
+
+A Catalog in Greenhouse holds the available PluginDefinitions and acts as the source of truth for which plugins can be deployed within an organization. When a catalog is not ready, it indicates that the catalog source cannot be synchronized or that the catalog controller is unable to process it correctly.
+
+This could be due to:
+
+- The catalog source (e.g. Helm repository, OCI registry) being unavailable or unreachable
+- Invalid or expired credentials for accessing the catalog source
+- A misconfigured catalog resource (e.g. wrong URL, invalid reference)
+- The catalog controller encountering errors during reconciliation
+- Network connectivity issues between the Greenhouse operator and the catalog source
+
+## Diagnosis
+
+### Get the Catalog Resource
+
+Retrieve the catalog resource to view its current status:
+
+```bash
+kubectl get catalog <catalog-name> -n <namespace> -o yaml
+```
+
+Or use kubectl describe for a more readable output:
+
+```bash
+kubectl describe catalog <catalog-name> -n <namespace>
+```
+
+### Check the Status Conditions
+
+Look at the `status.statusConditions` section in the catalog resource. Pay special attention to:
+
+- **Ready**: The main indicator of catalog health
+- **SourceSynced**: Indicates whether the catalog source was successfully synchronized
+
+### Check Controller Logs
+
+Review the Greenhouse controller logs for more detailed error messages:
+
+```bash
+kubectl logs -n greenhouse -l app=greenhouse --tail=100 | grep -i catalog # requires permissions on the greenhouse namespace
+```
+
+Or access your logs sink for Greenhouse logs.
+
+### List All Catalogs
+
+Check if multiple catalogs are affected:
+
+```bash
+kubectl get catalog -A
+```
