What you tried to do so far that hasn't worked? RedwoodHQ is just a framework. I think what you should focus on doing first is getting you appium environment set up and executing test scripts. Once you have that then it will be almost trivial to incorporate into RedwoodHQ actions based framework.
Basically, whatever is there for Selenium, I want to have it for Appium as well.
Can you help please?
