-Files and directories with a `.symlink` extension are symlinked to your home directory with the `.symlink` extension removed and a dot character prepended.
+The bootstrapper will create an implicit symlink for the dotfiles directory itself. It will always be symlinked to `$HOME/.dotfiles` (unless you [`git clone`d the dotfiles](#installation) there.) This makes it easier to refer to other dotfiles from within dotfiles as you can use a static path. For example, [my git mergetool scripts point to `$HOME/.dotfiles/git/tools`](https://github.com/agross/dotfiles/blob/master/git/gitconfig.symlink#L56).

+| `$HOME`   | Home directory for the operating system, e.g. `$HOME` for all Linux-style `$OSTYPE`s and `/c/Users/<you>/` for `$OSTYPE == 'windows'` |
