Unofficial guide to dotfiles on GitHub
tl;dr: Create a .gitignore in your ~ with an asterisk on the first line and `!.dotfilename` on subsequent lines; the asterisk means Git will ignore everything, and the ! means Git will un-ignore that specific file or directory. (Be sure to include the .gitignore file itself.) Use Git as normal and push. To deploy on another machine/account, the easiest method is to check out as normal into a temporary directory, then move the .git directory from that temporary directory into your ~ and run `git revert`. Git will see all of the missing dotfiles as changes to be reverted and revert them into existence.
