+- CRDs are in cmd/thv-operator/api/v1alpha1/mcpserver_types.go
+- After modifying the CRDs, the following changes need to be done:
+    - `task operator-generate`, `task operator-manifests` and `task crdref-gen`.
+    - it is important to run `task crdref-gen` inside cmd/thv-operator as the current directory
+- When committing a change that changes CRDs, it is important to bump the chart version in deploy/charts/operator-crds/Chart.yaml and deploy/charts/operator-crds/README.md
