...The concept is pretty much the same as bundles in a typical vim+pathogen setup. Antigen is to zsh, what Vundle is to vim. Antigen has reached a certain level of stability and has been used in the wild for around a couple of years. If you face any problems, please open an issue. The usage should be very familiar to you if you use Vundle. Open your zsh with this .zshrc and you should see all the bundles you defined here, getting installed. Once it’s done, you are ready to roll. The complete syntax for the antigen bundle command is discussed in the Commands page.
