+Completions for [zoxide](https://github.com/ajeetdsouza/zoxide). ``zoxide`` is a smarter cd command, inspired by z and autojump. It remembers which directories you use most frequently, so you can "jump" to them in just a few keystrokes. zoxide works on all major shells.
+
+## Usage
+
+```nushell
+use zoxide-completions.nu *
+```
+or
+```nushell
+source zoxide-completions.nu
+```
