+### Controller

 The main executable is a [custom controller][] that manages resources of kind
 [LoadTest][loadtest]. This controller must be deployed to the cluster before
 load tests can be run on it. For deployment information, see [deployment][]. The
 controller is implemented with [kubebuilder][].

+There is a set of [tools](tools/README.md) used to generate load test
 configurations, prepare prebuilt images and run batches of tests. These tools
 are used to run batches of tests for continuous integration.
