milanm/DevOps-Roadmap ? reverse-engineered prompt

Build me a polished DevOps Roadmap 2026 project that feels like a helpful learning guide for someone who wants to become a DevOps engineer.

I want a clear roadmap page with a big visual overview, a PDF download version, and a well structured README that walks through the main learning path from Git and one programming language, to Linux, networking, servers, containers, Kubernetes, infrastructure as code, CI and CD, monitoring, cloud, software engineering practices, and a small DevSecOps section too.

Make it easy to scan, with short explanations for each step and useful links to free learning resources where possible. Include a nice looking layout that works well on GitHub, and add the image files or placeholders so the roadmap can be viewed directly in the repo. If you need to look up current docs or best practices online while building it, go ahead. Keep it beginner friendly, practical, and not too hype driven.
