This is a way for the creator of a project to notify people who are currently using the project that there has been an update to the project itself. Basicall, the creator changes a cloud variable by 1, and all other users get that update, making their local version lower than the current version, updating their project with the fact that they need to re-load. Instructions in project. This can be a useful tool when testing cloud projects, as it will allow the other users to know when they should re-load without lots of comments.
