+# AGENTS.md - Starting Line Productions Shop Book
+
+This document helps agents understand this codebase and work effectively with it.
+
+## Project Overview
+
+This is a **mdBook** project that creates the Starting Line Productions (STL) Shop Guide - a comprehensive manual for a fabrication lab rental business. The project documents tools, equipment, supplies, and procedures across different shop areas (Cleanfab, Dirtyfab, E3ds, Kitchen, HPCLab, RackRental).
+
+## Essential Commands
+
+### Building the Book
+```bash
+mdbook build                # Build the book to `book/` directory
+mdbook serve               # Start live development server (usually on localhost:3000)
+mdbook clean               # Clean build artifacts
+```
+
+### PDF Generation (Optional)
+The `book.toml` contains commented PDF configuration. To generate PDF:
+1. Uncomment the `[output.pdf]` section in book.toml
+2. Ensure you have a Chromium-based browser installed
+3. Run `mdbook build`
+
+## Code Organization
+
+```
+├── src/                    # Source markdown files
+│   ├── SUMMARY.md         # Book structure/table of contents
+│   ├── welcome.md         # Introduction page
+│   ├── version-history.md # Version tracking
+│   └── [shop-area]-*.md   # Content files organized by shop area
+├── book.toml              # mdBook configuration
+└── SourceMaterialTomerge/ # Binary source files (ODT, PDF, etc.)
+```
+
+### Content Structure
+The book is organized by shop areas:
+- **Cleanfab**: Clean fabrication shop
+- **Dirtyfab**: Dirty fabrication shop  
+- **E3ds**: Electronics/3D printing area
+- **Kitchen**: Kitchen facilities
+- **HPCLab**: High Performance Computing Lab
+- **RackRental**: Server rack rental operations
+
+Each area has:
+- `*-overview.md`: Area introduction
+- `*-tools.md`: Available tools
+- `*-equipment.md`: Equipment inventory
+- `*-supplies.md`: Supplies list
+
+## File Naming Conventions
+
+- Use kebab-case for all filenames
+- Shop area prefixes: `cleanfab-`, `dirtyfab-`, `e3ds-`, `kitchen-`, `hpclab-`, `rackrental-`
+- Suffixes indicate content type: `-overview`, `-tools`, `-equipment`, `-supplies`
+- Standard files: `welcome.md`, `version-history.md`, `SUMMARY.md`
+
+## Content Patterns
+
+### Markdown Structure
+- Use ATX-style headers (`#`, `##`, etc.)
+- Include links to vendor/product documentation
+- Add equipment pictures when available (files stored in `SourceMaterialTomerge/`)
+
+### SUMMARY.md Structure
+- Must match actual files in `src/` directory
+- Order: Welcome → Version History → Safety/Security → Area-specific content
+- Use relative paths: `./filename.md`
+
+## Important Gotchas
+
+### Broken Links in SUMMARY.md
+There's a known issue in SUMMARY.md line 2: `[Version History](./version-history.)` should point to `./version-history.md` (missing `.md` extension).
+
+### File Extensions
+Ensure all markdown files in SUMMARY.md have the `.md` extension - mdBook requires exact matches.
+
+### SourceMaterialTomerge/
+This directory contains binary files (ODT, PDF, etc.) that are referenced in the content but not directly processed by mdBook.
+
+## Style Guidelines
+
+- Write comprehensive, detailed descriptions
+- Focus on reproducibility - aim for the lab to be fully reproducible by anyone
+- Include vendor documentation links
+- Add plenty of images to showcase the shop setup
+- Maintain consistent structure across shop areas
+
+## Testing
+
+After making changes:
+1. Run `mdbook build` to verify syntax is correct
+2. Run `mdbook serve` to check the book renders properly
+3. Check all internal links work in the generated book
+4. Verify SUMMARY.md entries point to existing files
