| description | Instructions for using Jujutsu (jj) for version control in the Carbon repository. |
Jujutsu is a Git-compatible version control system that may be used in Carbon checkouts.
[!IMPORTANT] You can detect if Jujutsu is in use by checking for a
.jjdirectory in the repository root. If present, you must usejjand must not usegit. If absent, you must not usejj.
Always use the --no-pager flag when invoking jj to prevent the command from
blocking or waiting for terminal paging.
