 ## Specifying `Parameters`
 
+(See also [Specifying Parameters in Tasks](tasks.md#specifying-parameters))
+
 You can specify global parameters, such as compilation flags or artifact names, that you want to supply
 to the `Pipeline` at execution time. `Parameters` are passed to the `Pipeline` from its corresponding
 `PipelineRun` and can replace template values specified within each `Task` in the `Pipeline`.

+Parameter declarations (within Tasks and Pipelines) can include default values which will be used if the parameter is
+not specified, for example to specify defaults for both string params and array params
+([full example](../examples/v1beta1/taskruns/array-default.yaml)) :

+```yaml
+apiVersion: tekton.dev/v1beta1
+kind: Task
+metadata:
