### How to Use the Shortcode:

Basic usage in pages or posts:
```
[vendor_store_url]
```

With custom link text:
```
[vendor_store_url text="Visit My Chef Store"]
```

With custom CSS class:
```
[vendor_store_url text="My Chef Profile" class="chef-button"]
```

### For Theme Developers:

To get just the URL in PHP (returns `#` if not applicable):
```php
<?php echo wbcom_get_wcfm_vendor_store_url(); ?>
```

For a specific user:
```php
<?php echo wbcom_get_wcfm_vendor_store_url($user_id); ?>
```

This code aligns with your existing practices in the theme and maintains the naming convention you're using with other functions like `wbcom_add_ld_instructor_role()`.
