Comment leads user to believe that adding NgsRevealConfig as a provider was necessary.

Hi @huckpilot ,

Adding NgsRevealConfig to providers list of the component IS necessary when you want to customize the settings for that component and its children. Of course, if you don't need any global customization, there is no need. That why this part is in a different section of the README.

What do you find misleading or unclear in the docs?

@tinesoft Thanks for the reply!

This may be an issue on my part.

my app.compoment.ts file:

import { NgsRevealConfig } from 'ng-scrollreveal';
...
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
  providers: [ContentfulService, NgsRevealConfig],
...
  constructor(
    private config: NgsRevealConfig
...
    config.scale = 1;
    config.opacity = 0;
    config.reset = true;

When I add NgsRevealConfig to my component provider, the global config values are not recognized site wide. However when I remove NgsRevealConfig from my component provider, the scroll reveal global config values are functioning.
