-If you installed kubeswitch correctly, you can run the command `switch` (zsh, bash) or `kubeswitch` (fish) or alternatively the alias `s` from the terminal.
+If you installed kubeswitch correctly, you can run the command `switch` (zsh, bash) or `kubeswitch` (fish, powershell) or alternatively the alias `s` from the terminal.
 In case the terminal can't find the function, you might need to open another terminal or re-source your config file (`.zshrc`,`.bashrc`,...).
 
 That should display the contexts the tool can find with the default configuration.
