Setup

jj setup

Install by following the installation instructions.

Tell jj how to author your commits. (It will complain when you run commands otherwise, so it's worth doing now.)

$ jj config set --user user.name "My Name"
$ jj config set --user user.emil "my@email.address"

If you run jj with no arguments, it prints a help message that suggests a default configuration that you should adopt.

$ jj
Hint: Use `jj -h` for a list of available commands.
Run `jj config set --user ui.default-command log` to disable this message.

So run that too:

$ jj config set --user ui.default-command log

Repo setup

To learn, you'll need a repository to run commands on. You can create a new repository or pick an existing Git repository so you have some real files to work with.

To create a new repository, create a new directory (or go to an existing directory already managed by Git) and:

$ jj git init

If you wanted to clone a Git repository, e.g. one from GitHub:

$ jj git clone <someurl>

This tutorial assumes you're starting with a fresh repository, but it will be almost the same if you clone an existing repository instead.
