   1 checkout.defaultRemote::
   2         When you run `git checkout <something>`
   3         or `git switch <something>` and only have one
   4         remote, it may implicitly fall back on checking out and
   5         tracking e.g. `origin/<something>`. This stops working as soon
   6         as you have more than one remote with a `<something>`
   7         reference. This setting allows for setting the name of a
   8         preferred remote that should always win when it comes to
   9         disambiguation. The typical use-case is to set this to
  10         `origin`.

  12 Currently this is used by linkgit:git-switch[1] and
  13 linkgit:git-checkout[1] when `git checkout <something>`
  14 or `git switch <something>`
  15 will checkout the `<something>` branch on another remote,
  16 and by linkgit:git-worktree[1] when `git worktree add` refers to a
  17 remote branch. This setting might be used for other checkout-like
  18 commands or functionality in the future.

  20 checkout.guess::
  21         Provides the default value for the `--guess` or `--no-guess`
  22         option in `git checkout` and `git switch`. See
  23         linkgit:git-switch[1] and linkgit:git-checkout[1].
