 `TestRun` CRD is a representation of a single k6 test, executed once. `TestRun` has a large support for configuration of different options that allows you to adapt to different Kubernetes setups. Full list of options can be found in the [definition itself](https://github.com/grafana/k6-operator/blob/main/config/crd/bases/k6.io_testruns.yaml).
 
-`PrivateLoadZone` CRD is a representation of a [load zone](https://grafana.com/docs/grafana-cloud/testing/k6/author-run/use-load-zones/): a k6 term for a set of nodes within a cluster designated to execute k6 test runs. `PrivateLoadZone` is integrated with [Grafana Cloud k6](https://grafana.com/products/cloud/k6/) and requires a subscription. There is a guide describing [how to set up `PrivateLoadZone`](https://grafana.com/docs/grafana-cloud/testing/k6/author-run/set-up-private-load-zones/), while billing details are described [here](TODO).
