Google Docs is a powerful online collaboration tool that enables multiple users to work simultaneously on a document.
Tracking changes and understanding the evolution of a document can be crucial for a variety of reasons, such as identifying the authors of changes, reverting to a previous version or simply reviewing the collaborative process.
Fortunately, Google Docs offers a comprehensive revision history feature that lets you easily view and manage changes made to your documents.
Here's a step-by-step guide to accessing and using this feature:
