 Open your zsh with this zshrc and run `bundle-install` and you should be ready

+## bundle-apply

+You have to add this command after defining all bundles you need, in your zshrc.
+The completions defined by your bundles will be loaded at this step.
+
+It is possible to load completions as and when a bundle is specified with the
+bundle command, in which case this command would not be necessary. But loading
+the completions is a time-consuming process and your shell will start noticeably
+slow if you have a good number of bundle specifications.
+
+However, if you're a zsh expert and can suggest a way so that this would not be
+necessary, I am very interested in discussing it. Please open up an issue with
+your details. Thanks.
