    // ...
    Phil\TaxonomyBundle\PhilTaxonomyBundle::class => ['all' => true],
];

# config/packages/phil_taxonomy.yaml
phil_taxonomy:
    fallback_locale: en   # the language of a name when there is none in the language asked
    slugger: ~            # the service id of the slugger of names and keys; ~ for the default one

With DoctrineBundle, the bundle maps its entities; the application's migrations create four tables:

Table	Columns
`phil_taxonomy_tag`	`id`, `name` (100), `slug` (128, unique)
`phil_taxonomy_category`	`id`, `category_key` (128, unique), `parent` (restricted on delete), `path` (420, indexed), `position`
`phil_taxonomy_category_translation`	`id`, `category` (cascades on delete), `locale` (16), `name` (150), `description`; unique on category and locale
`phil_taxonomy_assignment`	`id`, `term_type` (`tag` or `category`), `term_id`, `resource_kind` (64), `resource_id` (255); unique on all four, indexed on the resource
