Jujutsu (jj) Version Control Guide

Jujutsu is a modern, Git-compatible version control system. This project uses jj colocated with git.

Key Differences from Git

Concept Git Jujutsu
Staging area Explicit git add None - working copy IS a commit
Branches Named refs Bookmarks (auto-follow rewrites)
Stash Separate stash stack Not needed - just use commits
Amend git commit --amend Just edit files, or use jj squash
Identity Commit ID only Change ID (stable) + Commit ID

Essential Commands

Task Command
Status jj status or jj st
Diff jj diff
Log jj log
Commit & continue jj commit -m "message"
Update message jj describe -m "message"
New empty commit jj new
Squash into parent jj squash
Undo last operation jj undo
Fetch from remote jj git fetch
Push to remote jj git push

Working Copy Model

The working copy (@) is always a commit. File changes are automatically tracked - no staging required.

parent commit
    ↓
@ (working copy) ← your edits go here automatically
