You can clone the repository wherever you want. (I like to keep it in ~/Projects/dotfiles, with ~/dotfiles as a symlink.) The bootstrapper script will pull in the latest version and copy the files to your home folder.
git clone https://github.com/mathiasbynens/dotfiles.git && cd dotfiles && source bootstrap.shTo update, cd into your local dotfiles repository and then:
source bootstrap.shTo install these dotfiles without Git:
cd; curl -#L https://github.com/mathiasbynens/dotfiles/tarball/master | tar -xzv --strip-components 1 --exclude={README.md,bootstrap.sh,.osx,LICENSE-MIT.txt}To update later on, just run that command again.
Suggestions/improvements welcome!
