 ## Project Purpose & Structure
 - This repo is a hands-on .NET course for Generative AI, focused on real-world, runnable code and live coding.
-- Lessons are organized in numbered folders (e.g., `01-IntroToGenAI/`, `03-CoreGenerativeAITechniques/`), each with a `readme.md` and code in the root sample folder.
-- Key technologies: .NET 9+, Microsoft.Extensions.AI (MEAI), Microsoft Agent Framework, Azure OpenAI, Ollama (local models).
+- Lessons are organized in numbered folders (`01-IntroductionToGenerativeAI/` through `05-ResponsibleAI/`), each with a `readme.md` for documentation.
+- All code samples live in the centralized `samples/` directory, organized by category: `CoreSamples/`, `MAF/`, `AppsWithGenAI/`, `PracticalSamples/`.
+- Key technologies: .NET 10+, Microsoft.Extensions.AI (MEAI), Microsoft Agent Framework, Azure OpenAI, Ollama (local models).
 - Multi-language support: see `translations/` for localized docs.
 
 ## Architecture & Patterns
-- Each lesson is self-contained; (e.g., `05-AppCreatedWithGenAI/SpaceAINet/`) demonstrate full-stack AI integration.
-- Samples are created inside the sample folder for organization.
+- Each lesson folder contains documentation; code samples are in `samples/` (e.g., `samples/AppsWithGenAI/SpaceAINet/` demonstrates full-stack AI integration).
+- Samples are organized under `samples/` by category: `CoreSamples/`, `MAF/`, `AppsWithGenAI/`, `PracticalSamples/`.
 - AI model calls are always abstracted behind service classes (e.g., `SpaceAINet.GameActionProcessor`), enabling easy provider swapping and testability.
 - API keys and endpoints are never hardcoded—use user secrets or environment variables (see lesson READMEs for details).
 - For SpaceAINet and similar apps:

   - For local AI: ensure Ollama is running and the required model is pulled (e.g., `ollama pull phi4-mini`).
   - For Azure: set secrets via `dotnet user-secrets` or Codespaces secrets.
 - **Switching AI Providers:**
   - Most samples support toggling between local (Ollama) and cloud (Azure OpenAI) models at runtime (see app key bindings and README tables).
 - **Codespaces:**
   - Dev containers are pre-configured for .NET, Azure, and Ollama workflows. Choose the right container for your use case.
 - **Testing:**
-  - Run sample apps in the lesson `src/` folders to verify model integration and workflow.

 ## Code Standards & Best Practices
 - Follow C# and .NET best practices (naming conventions, async/await patterns, nullable reference types)
