+## Tab Completion
+
+### bash
+
+```bash
+echo 'eval "$(_RFD_COMPLETE=source rfd)"' >> ~/.profile
+```
+
+### zsh
+
+There isn't native support for zsh but zsh's bash completion compatibility mode works:
+
+```zsh
+echo 'autoload bashcompinit \
+bashcompinit \
+eval "$(_FOO_BAR_COMPLETE=source foo-bar)"' >> ~/.zshrc
 ```
