If you visit the following page at the Syncovery website, you'll see the proper instructions regarding the Google Cloud synchronization features.
Install the software, then follow the instructions below:
- Start the wizard and configure the folders (Left side is for local drive, right side is for Google Drive. Click the Globe to choose the Service.)

- Configure the way synchronization works (in the image is set up to sync from your local folder to online folder; choose my settings as well)

- Configure additional options for subfolders.

- Press Next and log-in to your Google Account.

So, right now everything you add on the local folder will be synchronized with the online cloud. It's only a one-way synchronization, but you can adjust settings if necessary as you've seen in these images.
