This seminar provides a practical introduction to modern AI coding assistants, with a focus on GitHub Copilot as the main tool used throughout the training. Participants will learn the core concepts behind LLM-based coding assistants, how to work with chat effectively, how to improve results through context and instructions, and how tools such as MCP expand what these systems can do inside real development workflows. Although the seminar is demonstrated with GitHub Copilot, the same core ideas apply to other coding agents and assistants as well.
