### Step 2: Adding `zoxide` to your shell ### Step 2: Adding `zoxide` to your shell
By default, `zoxide` defines the `z`, `zi`, `za`, `zq`, and `zr` aliases. If you'd like to go with just the barebones `z`, pass the `--no-define-aliases` flag to `zoxide init`.
#### zsh #### zsh
Using [antibody](https://github.com/getantibody/antibody): Add the following line to your `~/.zshrc`:
```sh ```sh
antibody bundle ajeetdsouza/zoxide eval "$(zoxide init zsh)"
``` ```
Using [zinit](https://github.com/zdharma/zinit): #### bash
Add the following line to your `~/.bashrc`:
```sh ```sh
zinit light ajeetdsouza/zoxide eval "$(zoxide init bash)"
``` ```
Using [antigen](https://github.com/zsh-users/antigen):
```sh
antigen bundle ajeetdsouza/zoxide
```
Using [zgen](https://github.com/tarjoilija/zgen):
```sh
zgen load ajeetdsouza/zoxide
```
Using [zplug](https://github.com/zplug/zplug):
```sh
zplug "ajeetdsouza/zoxide"
```
If you'd rather not use a package manager, add the contents of [zoxide.plugin.zsh](zoxide.plugin.zsh) to your `.zshrc`.
#### fish #### fish
Using [fisher](https://github.com/jorgebucaran/fisher): Add the following line to your `~/.config/fish/config.fish`:
```sh ```sh
