 Make authenticated Pesapal API calls without the fuss! Handles all the [oAuth
 stuff][1] abstracting any direct interaction with the API endpoints so that you
 can focus on what matters. _Building awesome_.
 
 This gem is work in progress. At the moment, the only functionality built-in is
 posting an order i.e. fetching the URL that is required to display the post-
 order iframe. Everything else should be easy to do as the groundwork has already
 been laid. If you are [feeling generous and want to contribute, feel free][9].

+The gem should be [up on RubyGems.org][7] and it's [accompanying RubyDoc reference][13] here.

 _Ps: No 3rd party oAuth library dependencies, it handles all the oAuth flows on
 it's own so it's light on your app._
