## Configuring Completions in `fish`
No configuration is needed in `fish`. Friendly!
No configuration is needed if you're using Homebrew's `fish`. Friendly!
If your `fish` is from somewhere else, add the following to your `~/.config/fish/config.fish`:
```sh
if test -d (brew --prefix)"/share/fish/completions"
set -g -x fish_complete_path $fish_complete_path (brew --prefix)/share/fish/completions
end
if test -d (brew --prefix)"/share/fish/vendor_completions.d"
set -g -x fish_complete_path $fish_complete_path (brew --prefix)/share/fish/vendor_completions.d
end
```
