# 4. Built on Git, for superior version control and data hosting

Every Authorea document is a Git repository you can interact with (i.e. push from, pull to, fork, etc). Our Git back-end has two major advantages: 1) All changes made to Authorea documents are tracked by Git i.e. one of the most robust version control systems. No longer will you need to track changes in Word. Version history of any document is integrated within the document itself. 2) Since every document in Authorea is a Git repository, you can include more than just text and images: data, code, videos, data visualizations, notebooks, workflows. Authorea creates web-native documents that allow you to integrate data, code and all the material needed to reproduce scientific results. This enables transparency and reproducibility, the very foundations of the scientific method. Authorea can allow the long-awaited leap that will push the scientific paper into the 21st century.
