What kind of documentation is this though? Is this how to bake a cake or tie a necktie, or is it how to setup a reverse proxy for the services in your k8s cluster?

If it's something a lay-person could do then I think this is a good strategy (though depending on the size/scope of the project/documentaiton it does seem like a pretty big effort to undertake without compensation), but if it's something highly technical like Traefik, I expect a lay-person to not even understand half the words/vocabulary in the documentation, let alone be able to perform X by reading it and following it.
