how to add a cookbook with no recipe to runlist in chef

I am trying to learn chef and cookbooks. All cookbooks I seen have a recipe. But this one ruby_rbenv have no recipes in source code. So in that case how can I use this?

I tried adding ruby_rbenv::system_install to runlist. But showing error that it cant find system_install in cookbook ruby_rbenv. Similarly if I try adding just ruby_rbenv to run_list it shows cant find default recipe error.

Could some one tell me how to do it in this case?

Here is the chef repo am working with now my repo

You don’t add it to your run list. That is what we call a “library cookbook”, one that only exists to be depended on by other cookbooks so they can use the custom resources it defines.
