title: Angular Schematics confusion
body: <p>Not sure to fully understand a concept with Angular Schematics. More precisly how to execute a schematic.
  Reading from some articles, I saw that we have to use <code>ng g my-schematics-collection:simple-schematic --name="some name"</code>.
  In other articles I saw <code>schematics  my-schematics-collection:simple-schematic --name="Angular Community"</code>.
  And again using <a href="https://nx.dev/" rel="nofollow noreferrer">NX</a>, they simple use <code>ng g component</code>, exactly like the base Angular Schematics to create a component. How can they overwrite the existing Angular Schematics? The fact that they doesn't point to their own schematics collection confuses me.</p>
  
  <p>Can someone explain what to use for what use cases?
  Thanks!</p>
