# Bootstraping the core library

You may want to run a minimal version of API Platform. This one file runs API Platform (without graphql, doctrine and mongodb).
It requires the following composer packages:

```console
composer require \
    api-platform/core \
    phpdocumentor/reflection-docblock \
    symfony/property-info \
    symfony/routing \
    symfony/validator
```

The minimal version of API Platform:
