...Done!

To manage dotfiles in the future, use the \`dotfiles\` alias with
\`git\` commands to, for example,
    - dotfiles pull                 (pull changes)
    - dotfiles push                 (push changes)
    - dotfiles add <file>           (add file to dotfiles repo)
    - dotfiles commit -am <msg>     (commit changes to dotfiles)

Bye!!
