Questions from @elixpoo

• Should the README.md be placed at app_templates/ or inside each example app directory?
• What sections should the template README require for new app templates?
• Should the README describe only the template structure, or also include usage and contribution guidance?
• Are both example_app_first and example_app_second expected to follow the same README format?
