some more documentation please

[wfalkwallace]

usage docs need some love 😿. how do I get my google_map_key (what I tried doesn't seem to be working)? what are available cards/is there a contributors collection? are there keyboard shortcuts? what does this give me more than alfred?

Hi @wfalkwallace , sorry for the frustration when it fails, totally understand. This project is still in a pretty early stage, so I am still working on it, a good documentation is super important.

I've added a valid-config to check the configuration, so now it will use info-card to show the config error message if missing api; I also added a FAQ section to readme, please let me know if it helps.
Thanks.
