To create a new version is as simple as adding a new column on your spreadsheet. In order for ContentSync to recognize this new version, you may need to trigger a "Update Versions from Spreadsheet" (see each specific plugin for more details).
Set Version to Not Be Syncable
Sometimes your spreadsheet may contain additional columns you do not want anybody to sync to. To prevent a version from being syncing, go to your project at contentsync.com, navigate to your project, go to settings > versions press the edit button next to a version. From there you can toggle the version you'd like to not be syncable.
Syncing A Version
To sync a design with a version requires you to install the ContentSync plugin of your choice. Once you have installed and configured it, you just select the version and sync.
Syncing a version can be done in both directions!
