puts 'Deployment in Ruby'

Common real-world use

Developers usually combine deployment with surrounding concepts such as project structure, debugging, testing, performance, security, or API work. That is why it is useful to learn both the syntax and the reason the topic exists.

Takeaway: Learn the purpose of deployment first, then practice it in small examples, and finally connect it to larger Ruby applications for stronger long-term understanding.
