TextExpander

Install the software here: http://smilesoftware.com/TextExpander/index.html

Then go to the RareWire documentation site and download our library here: https://studio.rarewire.com/wordpress/resources/

Then open TextExpander and click the plus button at the bottom left of the window and select "Add group from file"

This should ask you to upload the files contained in the zip that you downloaded from our site. 

Excellent! Thanks for your help.
