  + Now that pijul is installed and working on your system, you can set your

  + user name, full name, and e-mail address so you don’t have to set it each

  + time you want to record a change.

  + You can put this information into one of several places; the one you

  + probably want is `$HOME/.config/pijul/config.toml` (Linux), or

  + `~/.pijulconfig` (MacOS).

  +

  + Create the file and add the following lines to it:

  +

  + ```

  + [author]

  + name = "<username>"

  + full_name = "<full name>"

  + email = "<email address>"

  + ```

  +

  + From now on, pijul should pick this up when recording changes and pre-fill

  + the author section for you.
