+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Overview
+
+This is an IETF Internet-Draft repository for Media over QUIC (MOQ) protocol specifications authored by Luke Curley. It contains three draft documents:
+
+- **draft-lcurley-moq-lite.md**: A simplified MOQ transport protocol for real-time conferencing
+- **draft-lcurley-moq-hang.md**: Specification for handling connection hangs in MOQ
+- **draft-lcurley-moq-use-cases.md**: MOQ protocol use cases documentation
+
+## Build Commands
+
+```bash
+# Build all drafts (generates HTML and text versions)
+make
+
+# Clean build artifacts
+make clean
+
+# Update GitHub Pages (typically done via CI)
+make gh-pages
+```
+
+## Development Workflow
+
+1. **Prerequisites**: The build system requires i-d-template tools. See [setup instructions](https://github.com/martinthomson/i-d-template/blob/main/doc/SETUP.md).
+
+2. **Building drafts**: Running `make` will:
+   - Initialize the i-d-template submodule if needed
+   - Convert Markdown drafts to RFC XML format
+   - Generate HTML and text versions
+   - Output files: `draft-*.html` and `draft-*.txt`
+
+3. **Git workflow**:
+   - Main branch: `main`
+   - Pull requests automatically trigger CI builds
+   - GitHub Pages updates on push to main
+
+## Architecture
+
+This is a standards documentation project, not a software implementation. Key components:
+
+- **Draft documents**: Root-level `draft-*.md` files in kramdown-rfc format
+- **Build system**: Uses i-d-template via git submodule in `lib/`
+- **CI/CD**: GitHub Actions workflows handle building and publishing
+- **Output**: Published to GitHub Pages at https://kixelated.github.io/moq-drafts/
+
+## Working Group Context
+
+- Part of IETF Media Over QUIC (MOQ) Working Group
+- Discussion: moq@ietf.org mailing list
+- Related to main MoqTransport specification (moq-lite is a simplified alternative)
+
+## Important Notes
+
+- Follow IETF contribution guidelines (BCP 78/79)
+- Draft format uses kramdown-rfc with YAML frontmatter
+- References are managed via bibxml includes
+- Do not edit generated files (*.html, *.txt)
