Add following content to .zshrc.

autoload -Uz compinit bashcompinit
compinit
bashcompinit

Completions should be correctly installed by your package manager. If not, run as root:

mkdir /usr/local/share/zsh/site-functions
rg --generate=complete-zsh >/usr/local/share/zsh/site-functions/_rg

git's completion file is shipped with zsh, while rg's is not.

You should install it manually, especially when you install rg by cargo.
