 You can customize the shell script that gets generated by using these options:
 
-| Option | Default | Description |
-| ------ | ------- | ----------- |
-| `--cd-cmd` | `builtin cd` | Define the command to be used instead of `cd`. (e.g. `--cd-cmd=z`) |
-| `--cmd`| `y` | The name of the main lacy command you use for navigating. (e.g. `--cmd=cd`) |
-| `--custom-fuzzy` | *none* | Configure this to disable lacy's built in UI selector and replace it with your own command. (e.g. `--custom-fuzzy=fzf`) |
+### `--cd-cmd`
+
+Define the command to be used instead of `cd`. (e.g. `--cd-cmd=z`)
+
+Default:
+
+- Bash, ZSH, Fish: `builtin cd`
+- Nushell: `cd`
+- PowerShell: `Set-Location`
+
+### `--cmd`
+
+The name of the main lacy command you use for navigating. (e.g. `--cmd=cd`)
+
+Default: `y`
+
+> [!WARNING]
+> Nushell doesn't have a `builtin cd` option,
+> so setting it `--cmd=cd` will cause a loop.
+> It should be possible to bypass this with some tinkering ([issue in nushell repo](https://github.com/nushell/nushell/issues/3792)). Feel free to open a PR if you have a good solution!
