    The "examples" directory has been installed to:
      #{HOMEBREW_PREFIX}/share/awscli/examples

    Add the following to ~/.bashrc to enable bash completion:
      complete -C aws_completer aws

    Add the following to ~/.zshrc to enable zsh completion:
      source #{HOMEBREW_PREFIX}/share/zsh/site-functions/_aws

    Before using awscli, you need to tell it about your AWS credentials.
    The easiest way to do this is to run:
      aws configure
