I am trying to find the listing of descriptions, valid and default values for playbook play parameters similar to the module index that lists these for each of the modules. Can anyone point me in the correct direction? Thanks
you mean like “name”, “hosts”, “tasks”, “roles” and such? Good question, I don’t know if that’s properly organized anywhere.
Yes, those (and other parameters at the same level on plays, like become, gather_facts, and run_once) are what I am looking for. It’s unfortunate that they are not listed anywhere it would be very helpful, especially for people new to Ansible.
Well, I first looked into
<http://docs.ansible.com/ansible/playbooks_intro.html>, and followed the
links mentioned there 
I'm lacking time to do real deep research, so I'm still not good at
playbooks, but up to now they do what I want, even it it takes me quite
some time to get there :).

They are now listed, but no additional information, yet http://docs.ansible.com/ansible/playbooks_directives.html
This is definitely a good start and provides a leaping off point to discover what these do. It is listing far more than I thought there was by reading through the other documentation on the site, very informative.
