+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+DevDen is a self-hosted AI chat platform that enables organizations to provide AI-powered Q&A based on their own knowledge bases. Users interact through a clean chat interface while administrators manage knowledge bases, AI providers, and user access through a terminal-style dashboard.
+
+**Current Status:** Early prototype stage with static frontend (HTML/CSS/JS). Backend infrastructure is not yet implemented.
+
+## Architecture
+
+**Planned Technology Stack:**
+- **Frontend:** Vanilla JavaScript (prototype), potential migration to Svelte
+- **Backend:** FastAPI (Python)
+- **Database:** PostgreSQL (users, conversations, settings)
+- **Cache:** Redis (sessions)
+- **Vector DB:** Qdrant or ChromaDB (semantic search)
+- **Auth:** Microsoft Entra ID
+- **AI Providers:** Claude, OpenAI, Gemini, OpenRouter, Ollama (local)
+
+**Two-Interface Design:**
+- Clean chat interface for end users (warm, accessible design)
+- Terminal-style dashboard for administrators
+
+## Current Files
+
+- `index.html` - Main chat interface structure
+- `script.js` - Chat interaction logic (mock responses currently)
+- `style.css` - UI styling with fox-themed color scheme (accent: `#d4a574`)
+
+## Development Phases (from project.md)
+
+1. Core Chat - Basic chat with single AI provider
+2. Knowledge Base - Document indexing and semantic search
+3. Authentication - Microsoft Entra ID integration
+4. Admin Dashboard - Management interface
+5. Multi-Provider - Multiple AI provider support
+6. Git Integration - Auto-sync from repositories
+7. Polish - Production readiness
+
+## Commands (Future)
+
+When Docker infrastructure is implemented:
+```bash
+docker-compose up -d
+docker-compose exec devden-web python manage.py init-db
+docker-compose exec devden-web python manage.py create-admin --email admin@company.com
+docker-compose logs -f devden-web
+```
+
+## Design Decisions
+
+- Knowledge bases connect via Git repositories (auto-sync) or Docker volumes (local files)
+- Source transparency: answers show which documents were referenced
+- User quotas configurable per-user (questions per day/month)
+- API keys encrypted at rest
+- All data stays on-premises (self-hosted)
