How do I create a simple Angular component?

<!-- BEGIN COPY / PASTE -->
        import { Component } from '@angular/core';

        @Component({
          selector: 'app-simple',
          template: `
            <div>
              <h1>Hello, Angular!</h1>
              <p>This is a simple component.</p>
            </div>
          `,
          styles: [`
            div {
              text-align: center;
              margin: 20px;
            }
          `]
        })
        export class SimpleComponent {}
        <!-- END COPY / PASTE -->
