Hi surfculturecanada,
You’ll first need to extract the zip file downloaded after your purchase. Inside, it contains two zipped packages – one is the mobile theme (and should be installed as a theme) and another is a helper plugin (and should be installed as a plugin).
We’ve provided the installation instructions at this link:

Let me know if you need further assistance. We do provide complimentary installation service if required.
