Documentation is unclear where factory providers arguments are coming from

[cowboyd]

Describe the bug
In this doc https://github.com/Urigo/graphql-modules/blob/master/website/docs/di/providers.md#factory

The factory has a dependency Config which is used as a value, but then also used as a type in the argument of the factory. It's not clear what the value or the type is from the code examples. The prose explaining the code example do not explain what these values and types are.

Expected behavior

It should be clear what the values and types represent and where they are coming from.

Environment:

website

It actually comes from deps;

  useFactory(config: Config) {
    if (config.environment === 'production') {
      return 'my-api-key';
    }

    return null;
  },
  deps: [Config] // <<Here

Would you create a PR on the documentation to make it clear?

[cowboyd]

@ardatan where does the value Config in the expression [Config] come from?

[ardatan]

It is the injection token, class itself or custom injection token defined in providers

I see. It would probably benefit from having an import statement to define the reference to the value in the docs.
