 ## Start the app
 
 To start the development server run `nx serve datahub`. Open your browser and navigate to http://localhost:4200/. Happy coding!
 
-
 ## Generate code
 
 If you happen to use Nx plugins, you can leverage code generators that might come with it.
 
+To generate a component from the root dir for instance, run the following command:
+
+```
+npx nx g @nx/angular:component [my-component] --module=app.module --directory=apps/datahub/src/app/[my-component-location]
+```
+
 Run `nx list` to get a list of available plugins and whether they have generators. Then run `nx list <plugin-name>` to see what generators are available.
