+      The GoogleFlightsAgent will tell you the minimum airline prices between a pair of cities.
 
-      Follow their documentation here (https://developers.google.com/qpx-express/v1/prereqs#get-a-google-account) to retrieve an api key.
+      Follow the documentation [here](https://developers.google.com/qpx-express/v1/prereqs#get-a-google-account) to retrieve an api key.
       After you get to the google developer console, created a project, enabled qpx express api then you can choose `api key` credential to be created.
+      Note that at present you're limited to 50 queries per day free and after that are billed $0.035 per query.
 
       The `origin` and `destination` options require an [airport code](http://www.expedia.com/daily/airports/AirportCodes.asp).
 
       All the default options must exist. For `infantInSeatCount`, `infantInLapCount`, `seniorCount`, and `childCount`, leave them to the default value of `0` if you do not need them.
 
-      Make sure `date` and `return_date` is in this date format: `YYYY-MM-DAY`.
+      Make sure `date` and `return_date` is in this date format: `YYYY-MM-DAY`. You can use liquid formatting to dynamically assign a date in the future. For example to set the departure date 21 days from today, you'd use `{% assign current_date = 'now' | date: '%s' %}{{current_date | plus: 1814000 | date: '%Y-%m-%d'}}`
 
       You can choose one way tickets only by setting `roundtrip` to `false`.
 
+      You can limit to specific airlines using the `permittedCarrier` option and the two-letter IATA airline codes of choice. [https://en.wikipedia.org/wiki/List_of_airline_codes](https://en.wikipedia.org/wiki/List_of_airline_codes). Multiple airlines can be chosen, separated by commas.
+      
+      You can alternately limit your search to a specific set of airlines with the `alliance` option, to choose among the three Google-recognized ones, ONEWORLD, STAR and SKYTEAM.
+
       You can limit the number of `solutions` returned. The first solution will be the lowest priced ticket.
