FAQPage Schema

How do I rewrite Git history safely without dealing with a staging area?▼

Parallel agent version control is supported through dedicated isolated workspaces and robust conflict handling, enabling multiple agents to work simultaneously. This reduces manual merge pain and drift between teammates in collaborative projects.

Can I use jj with my existing Git repositories and remote bookmarks?▼

Yes, jj integrates strongly with Git by supporting automatic import and export, including remote bookmarks. This allows you to blend jj workflows into existing Git-based collaborative projects without abandoning your current infrastructure.

How do I start a new project with automatic change tracking in jj?▼

To start a new project, you create a jj-managed repository, make a sequence of commits on an isolated workspace, and then push the final bookmark stack to a remote. Changes auto-snapshot as you work without manual staging.

What are the limitations of using a rewrite-friendly VCS for version control?▼

Using a rewrite-friendly VCS requires managing hybrid workflows through automatic Git import and export. Users must adhere to specific agent rules and include required frontmatter metadata, which adds structural constraints to collaborative version control.
