-## Shell Completions

-The install script offers to set this up interactively. To do it manually, write the completion code to your shell's standard auto-load location:
-
-```bash
-# bash
-chatwoot completion bash -c > ~/.local/share/bash-completion/completions/chatwoot
-
-# fish
-chatwoot completion fish -c > ~/.config/fish/completions/chatwoot.fish
-
-# zsh — resolve the install path once so future PATH changes can't hijack the source line
-chatwoot_bin="$(command -v chatwoot)"
-echo "source <(\"$chatwoot_bin\" completion zsh -c)" >> ~/.zshrc
