# 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` |
| Create & push bookmark | `jj git push --named name=@` |
| Push existing bookmark | `jj git push --bookmark name` |
## 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
```
## Quick Git-to-Jujutsu Translation
| Git | Jujutsu |
|-----|---------|
| `git status` | `jj st` |
| `git diff` | `jj diff` |
| `git log` | `jj log` |
| `git add . && git commit -m "msg"` | `jj commit -m "msg"` |
| `git push` | `jj git push` |
| `git pull` | `jj git fetch` then `jj rebase -d main@origin` |
| `git checkout -b branch` | `jj new main` then `jj bookmark set branch` |
| `git branch` | `jj bookmark list` |
| `git stash` | `jj new` (just start new commit) |
| `git blame` | `jj file annotate` |
