+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+KubernetesLabs is a hands-on Kubernetes learning repository with 33+ numbered labs and 7 task collections. Content is published as an MkDocs Material site at https://nirgeier.github.io/KubernetesLabs/.
+
+## Build & Serve Commands
+
+```bash
+# Install dependencies
+pip install -r mkdocs/requirements.txt
+
+# Local development server (http://localhost:8000)
+mkdocs serve --config-file mkdocs.yml
+
+# Build static site (output: mkdocs-site/)
+mkdocs build --config-file mkdocs.yml
+
+# Deploy to GitHub Pages (done automatically by CI on push to main/master)
+mkdocs gh-deploy --force --clean --config-file mkdocs.yml --no-history
+```
+
+## Architecture
+
+### MkDocs Configuration
+
+The single `mkdocs.yml` at root is a merged file containing all config sections. The modular source files live in `mkdocs/`:
+
+- `01-mkdocs-site.yml` - Site metadata (name, URL, author)
+- `02-mkdocs-theme.yml` - Material theme settings
+- `03-mkdocs-extra.yml` - Social links, extra CSS/JS
+- `04-mkdocs-plugins.yml` - Plugins (git-committers, search, minify, print-site, include-markdown)
+- `05-mkdocs-extensions.yml` - Markdown extensions (pymdownx, mermaid, admonitions, tabs)
+- `06-mkdocs-nav.yml` - Navigation structure
+
+**Important:** `docs_dir` is set to `Labs` - all content lives under `Labs/`.
+
+### Lab Structure
+
+Each lab follows this pattern:
+```
+Labs/XX-TopicName/
+├── README.md          # Main lab content (this is the MkDocs page)
+├── manifests/         # Kubernetes YAML files
+├── scripts/           # Shell automation scripts
+└── [Dockerfile, etc.]
+```
+
+Tasks live in `Labs/Tasks/Kubernetes-*-Tasks/README.md`.
+
+### Navigation
+
+When adding a new lab, update the nav in both:
+- `mkdocs.yml` (the merged config)
+- `mkdocs/06-mkdocs-nav.yml` (the source file)
+
+## Lab README Conventions
+
+- Start with optional YAML frontmatter
+- Include sections: description, "What will we learn?", "Official Documentation & References" (table format), "Prerequisites", then numbered content sections (01, 01.01, etc.)
+- Use `=== "macOS"` / `=== "Linux"` tab syntax for platform-specific instructions
+- Use admonitions (`!!! note`, `!!! warning`, `!!! tip`) for callouts
+- Use mermaid fenced blocks for architecture diagrams
+- Code blocks use language hints: `bash`, `yaml`, `go`, `dockerfile`
+
+## CI/CD
+
+GitHub Actions (`.github/workflows/deploy-mkdocs.yml`) deploys on push to `main` or `master`. Requires Python 3.11, full git history (`fetch-depth: 0`), and `mkdocs/requirements.txt`.
+
+## Commit Message Convention
+
+Follow the pattern: `labXX: <description>` (e.g., `lab32: Add EFK stack`).
