Configuring self-signed cert for private registry - Documentation

[x8-ball]

Hi,
I'm having problems integrating the client certificate for Tekton. It is not clear to me from the documentation what is meant by this section. Does it refer to the folder structure of the worker node or is it in a deployment of Tekton itself? Unfortunately, I can't find an answer to this question online.

For reference im talking about this section https://tekton.dev/docs/installation/additional-configs/#configuring-self-signed-cert-for-private-registry

Any help would be really appreciated.
