You use it to get a copy of your code, track changes\nto the code, and finally publish those changes for others to see and use.\nIt is designed from the ground up to be easy to use\u2014whether you\u0027re new or\nexperienced, working on brand new projects alone, or large scale software\nprojects with large histories and teams.\n\nJujutsu is unlike most other systems, because internally it abstracts the user\ninterface and version control algorithms from the *storage systems* used to\nserve your content. This allows it to serve as a VCS with many possible physical\nbackends, that may have their own d",

It can interoperate with Git repositories, making it a drop-in alternative for teams wanting Git compatibility without Git\u0027s workflow constraints."
