Open Cart Theme chane

I have a clean install of OpenCart on Google Cloud. I need to install OpenCart Journal theme. Please have previous experience of doing this on Google cloud. Not local or AWS servers. Theres tricks to doing this on Google cloud (no FTP). Pointing the install to my Stripe account would be a plus/extra. We will do this with you screen-sharing (TeamViewer or Google) and uploading theme and config. from my screen logged into Google dashboard.
