## Overview

This repository is a GitHub Actions course: its main product is a collection of workflow examples and learning material for CI/CD and DevSecOps. Learners explore workflow triggers and reusable workflows, then examples covering .NET and web-app deployment, containers, Azure, Kubernetes, and runner configuration. A small ASP.NET Core MVC app is also present as an application example. Workflow files were not sampled, so their internal job steps and connections are not asserted; the app links below reflect only the sampled source.
