The Docker Workflow documentation is structured as a tutorial/introduction on how to use the plugin. Because of this finding all the arguments a function can have, and finding all the functions an object has is difficult, if they are all listed in that documentation.

A reference documentation page would greatly help with finding the information needed about how to use the functionality this plugin provides. For example check any of the declarative pipeline steps documentation: https://jenkins.io/doc/pipeline/steps/kubernetes-pipeline-steps/.
