-The `@2` stands for bash-completion 2, which is required by the kubectl completion script (it doesn't work with bash-completion 1). In turn, bash-completion 2 requires Bash 4.1+, that's why you needed to upgrade Bash.

 ### Enable kubectl autocompletion
 
-You now need to ensure that the kubectl completion script gets sourced in all your shell sessions. There are multiple ways in which you can do this:
+If you installed kubectl with Homebrew (as explained [here](#install-with-homebrew-on-macos)), then the completion script was automatically installed to `/usr/local/etc/bash_completion.d/kubectl`. In that case, you don't need to do anything.
 
-- Source the completion script in your `~/.bashrc` file:
-
-    ```shell
-    echo 'source <(kubectl completion bash)' >>~/.bashrc
-

+If you didn't install through homebrew you now need to ensure that the kubectl completion script gets sourced in all your shell sessions as follows:
 
 - Add the completion script to `/usr/local/etc/bash_completion.d`:
 
     ```shell
     kubectl completion bash >/usr/local/etc/bash_completion.d/kubectl
     ```
