 Benchmarks need to specify at least one supported load and resource type for which scalability can be benchmarked.
 
 Load and resource types are described by a name (used for reference from an Execution) and a list of patchers.
+Patchers can be seen as functions, which take a value as input and modify a Kubernetes resource in a patcher-specific way. Examples of patchers are the *ReplicaPatcher*, which modifies the replica specification of a deployment, or the *EnvVarPatcher*, which modifies an environment variable.
+See the [patcher API reference](api-reference/patchers) for an overview of available patchers.
+
 If a benchmark is [executed by an Execution](running-benchmarks), these patchers are used to configure SUT and load generator according to the [load and resource values](creating-an-execution) set in the Execution.

 Use the `removeOnly: True` property for topics which are created automatically by the SUT.
 For those topics, also wildcards are allowed in the topic name.
