I am newish to Sage and `composer`. I have a working Sage 8 theme, and I am trying to install [https://github.com/spatie/enum](https://github.com/spatie/enum).

I ran:

```
theme-folder> composer require spatie/enum
theme-folder> php composer.phar install
```

I see all the files in the `vendor` folder

```
theme-folder
│ composer.json
│
└───vendor
│ │ autoload.php
│ │
│ └───composer
│ │ ...
│ │
│ └───spatie
│ └───enum
│ │ composer.json
│ │ ...
```

However, when I load a page, I get errors when I try to reference the namespace:

```
PHP Fatal error: Class 'Spatie\Enum\Enum' not found in /var/www/wp-content/themes/theme-folder/lib/enums.php on line 9
```

I believe I need to include the files, but I’m not sure on the correct approach
