      Let's set up Git, a way to track the code that you write tomorrow.

      'git config --global user.name "First Name Last Name"'

    message <<-MARKDOWN
      The `--global` option tells Git to set your name system-wide, instead of in only
      one place.

      Now let's tell Git what your email is.
    MARKDOWN

    console_with_message(
      "Type the following, replacing the email with your email in the quotes:",
      'git config --global user.email "[email protected]_email.com"'

    message "> Initialized empty Git repository in /vagrant/railsbridge/suggestotron/.git/"

    message "It doesn't look like anything really happened, but `git init` created (or initialized) a Git repository in a hidden directory called `.git`. You can see the `.git` directory by typing `ls -a` to list all files."

    tip "git add" do
      message <<-MARKDOWN
        With Git, there are usually many ways to do very similar things.

        * `git add foo.txt` adds a file named `foo.txt`
        * `git add .` adds all new files and changed files, but *doesn't touch* files that you've deleted
        * `git add -A` adds everything, including deletions

        "Adding deletions" may sound weird, but if you think of a version control system as keeping
        track of *changes*, it might make more sense. Most people use `git add .` but `git add -A`
        can be safer. No matter what, `git status` is your friend.

explanation do
  message <<-MARKDOWN
By checking your application into git now, you're creating a record of this as your starting point. Whenever you make a change after today's workshop,  add it to git. This way, if anything ever breaks, or you make a change you don't like, you can use git as an all-powerful "undo" technique. But that only works when you remember to commit early and often!
