Introducing gitfs
The document discusses GitFS, an open-source project that integrates a file system with Git functionalities. It outlines technical aspects of its implementation using the pygit2 library, including repository cloning, data handling, and conflict resolution. Additionally, it provides commands for installation and mentions key statistics about the project's development.
