-Grafana's Prometheus-operator converter is on, so any chart shipping a
-`ServiceMonitor`/`PodMonitor`/`PrometheusRule` is scraped automatically.
+VictoriaMetrics Operator 的 Prometheus converter 已启用；官方
+`prometheus-operator-crds` chart 由 `operator/` 一并管理。因此应用 chart 可以原生
+声明 `ServiceMonitor`、`PodMonitor` 或 `PrometheusRule`，再由 converter 转换为对应
+VM 资源，不需要每个应用额外维护一份 `VM*Scrape`。
