+# Matrix Presi Bot - Claude Code Guidelines
+
+## Overview
+
+Matrix Presi Bot provides presentation management via Matrix chat. It integrates with the Presi backend for deck/slide management, theming, and sharing.
+
+## Tech Stack
+
+- **Framework**: NestJS 10
+- **Matrix**: matrix-bot-sdk
+- **Backend**: Presi API (port 3008)
+- **Auth**: Mana Core Auth (JWT)
+
+## Commands
+
+```bash
+# Development
+pnpm install
+pnpm start:dev        # Start with hot reload
+
+# Build
+pnpm build            # Production build
+
+# Type check
+pnpm type-check       # Check TypeScript types
+```

+
+# Run
+docker run -p 3325:3325 \

+  matrix-presi-bot
+```
+
+## Health Check
+
+```bash
+curl http://localhost:3325/health
+```
+
+## Presi Backend API Endpoints Used
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/health` | GET | Health check |
+| `/api/decks` | GET | List presentations |
+| `/api/decks` | POST | Create presentation |
+| `/api/decks/:id` | GET | Get presentation with slides |
+| `/api/decks/:id` | PUT | Update presentation |
+| `/api/decks/:id` | DELETE | Delete presentation |
+| `/api/decks/:id/slides` | POST | Add slide |
+| `/api/slides/:id` | DELETE | Delete slide |
+| `/api/themes` | GET | List themes |
+| `/api/share/deck/:id` | POST | Create share link |
+| `/api/share/deck/:id/links` | GET | List share links |
+
+## Number-Based Reference System
+
+The bot uses a number-based reference system for ease of use:
+1. User runs `!presis` or `!themes` to get a list
+2. Bot stores the list internally for the user
+3. User can reference items by their list number
+4. Numbers are valid until the user runs a new list command
+
+This allows simple commands like:
+- `!presi 2` - Show presentation #2
+- `!folie 1 titel Hallo` - Add slide to presentation #1
+- `!theme 1 3` - Apply theme #3 to presentation #1
