+## How It Works
 
--   **LLM-Powered Diagram Creation**: Leverage Large Language Models to create and manipulate draw.io diagrams directly through natural language commands
--   **Image-Based Diagram Replication**: Upload existing diagrams or images and have the AI replicate and enhance them automatically
--   **PDF & Text File Upload**: Upload PDF documents and text files to extract content and generate diagrams from existing documents
--   **AI Reasoning Display**: View the AI's thinking process for supported models (OpenAI o1/o3, Gemini, Claude, etc.)
--   **Diagram History**: Comprehensive version control that tracks all changes, allowing you to view and restore previous versions of your diagrams before the AI editing.
--   **Interactive Chat Interface**: Communicate with AI to refine your diagrams in real-time
--   **Cloud Architecture Diagram Support**: Specialized support for generating cloud architecture diagrams (AWS, GCP, Azure)
--   **Animated Connectors**: Create dynamic and animated connectors between diagram elements for better visualization
+The application uses the following technologies:
 
-## MCP Server (Preview)
+-   **Next.js**: For the frontend framework and routing
+-   **Vercel AI SDK** (`ai` + `@ai-sdk/*`): For streaming AI responses and multi-provider support
+-   **react-drawio**: For diagram representation and manipulation
 
-> **Preview Feature**: This feature is experimental and may not stable.
+Diagrams are represented as XML that can be rendered in draw.io. The AI processes your commands and generates or modifies this XML accordingly.
 
-Use Next AI Draw.io with AI agents like Claude Desktop, Cursor, and VS Code via MCP (Model Context Protocol).
+## Multi-Provider Support

-### Claude Code CLI
+All providers except AWS Bedrock and OpenRouter support custom endpoints.
 
-```bash
-claude mcp add drawio -- npx @next-ai-drawio/mcp-server@latest
-```
+📖 **[Detailed Provider Configuration Guide](./docs/ai-providers.md)** - See setup instructions for each provider.
 
-Then ask Claude to create diagrams:
-> "Create a flowchart showing user authentication with login, MFA, and session management"
+**Model Requirements**: This task requires strong model capabilities for generating long-form text with strict formatting constraints (draw.io XML). Recommended models include Claude Sonnet 4.5, GPT-4o, Gemini 2.0, and DeepSeek V3/R1.
 
-The diagram appears in your browser in real-time!
-
-See the [MCP Server README](./packages/mcp-server/README.md) for VS Code, Cursor, and other client configurations.
+Note that `claude-sonnet-4-5` has trained on draw.io diagrams with AWS logos, so if you want to create AWS architecture diagrams, this is the best choice.
 
 ## Getting Started
 
-### Try it Online
-
-No installation needed! Try the app directly on our demo site:
-
-[![Live Demo](./public/live-demo-button.svg)](https://next-ai-drawio.jiang.jp/)
-
-> Note: Due to high traffic, the demo site currently uses minimax-m2. For best results, we recommend self-hosting with Claude Sonnet 4.5 or Claude Opus 4.5.
-
-> **Bring Your Own API Key**: You can use your own API key to bypass usage limits on the demo site. Click the Settings icon in the chat panel to configure your provider and API key. Your key is stored locally in your browser and is never stored on the server.
-
-### Desktop Application
-
-Download the native desktop app for your platform from the [Releases page](https://github.com/DayuanJiang/next-ai-draw-io/releases):
-
-| Platform | Download |
-|----------|----------|
-| macOS | `.dmg` (Intel & Apple Silicon) |
-| Windows | `.exe` installer (x64 & ARM64) |
-| Linux | `.AppImage` or `.deb` (x64 & ARM64) |
-
-**Features:**
-- **Secure API key storage**: Credentials encrypted using OS keychain
-- **Configuration presets**: Save and switch between AI providers via menu
-- **Native file dialogs**: Open/save `.drawio` files directly
-- **Offline capable**: Works without internet after first launch
-
-**Quick Setup:**
-1. Download and install for your platform
-2. Open the app → **Menu → Configuration → Manage Presets**
-3. Add your AI provider credentials
-4. Start creating diagrams!
-

--   **基于图像的图表复制**：上传现有图表或图像，让AI自动复制和增强
--   **PDF和文本文件上传**：上传PDF文档和文本文件，提取内容并从现有文档生成图表
--   **AI推理过程显示**：查看支持模型的AI思考过程（OpenAI o1/o3、Gemini、Claude等）
--   **图表历史记录**：全面的版本控制，跟踪所有更改，允许您查看和恢复AI编辑前的图表版本
--   **交互式聊天界面**：与AI实时对话来完善您的图表
--   **云架构图支持**：专门支持生成云架构图（AWS、GCP、Azure）

 VALIDATION RULES (XML will be rejected if violated):
-1. Generate ONLY mxCell elements - NO wrapper tags (<mxfile>, <mxGraphModel>, <root>)
-2. Do NOT include root cells (id="0" or id="1") - they are added automatically
-3. All mxCell elements must be siblings - never nested
-4. Every mxCell needs a unique id (start from "2")
-5. Every mxCell needs a valid parent attribute (use "1" for top-level)
-6. Escape special chars in values: &lt; &gt; &amp; &quot;
+1. All mxCell elements must be DIRECT children of <root> - never nested
+2. Every mxCell needs a unique id
+3. Every mxCell (except id="0") needs a valid parent attribute
+4. Edge source/target must reference existing cell IDs
+5. Escape special chars in values: &lt; &gt; &amp; &quot;
+6. Always start with: <mxCell id="0"/><mxCell id="1" parent="0"/>

-### Vercel AI Gateway
-
-Vercel AI Gateway provides unified access to multiple AI providers through a single API key. This simplifies authentication and allows you to switch between providers without managing multiple API keys.
-
-**Basic Usage (Vercel-hosted Gateway):**
-
-```bash
-AI_GATEWAY_API_KEY=your_gateway_api_key
-AI_MODEL=openai/gpt-4o
-```
-
-**Custom Gateway URL (for local development or self-hosted Gateway):**

-```bash
-AI_GATEWAY_API_KEY=your_custom_api_key
-AI_GATEWAY_BASE_URL=https://your-custom-gateway.com/v1/ai
-AI_MODEL=openai/gpt-4o
-```
-
-Model format uses `provider/model` syntax:
-
--   `openai/gpt-4o` - OpenAI GPT-4o
--   `anthropic/claude-sonnet-4-5` - Anthropic Claude Sonnet 4.5
--   `google/gemini-2.0-flash` - Google Gemini 2.0 Flash
-
-**Configuration notes:**
-
--   If `AI_GATEWAY_BASE_URL` is not set, the default Vercel Gateway URL (`https://ai-gateway.vercel.sh/v1/ai`) is used
--   Custom base URL is useful for:
-    -   Local development with a custom Gateway instance
-    -   Self-hosted AI Gateway deployments
-    -   Enterprise proxy configurations
--   When using a custom base URL, you must also provide `AI_GATEWAY_API_KEY`
-
-Get your API key from the [Vercel AI Gateway dashboard](https://vercel.com/ai-gateway).

 **Note on Ollama**: While Ollama is supported as a provider, it's generally not practical for this use case unless you're running high-capability models like DeepSeek R1 or Qwen3-235B locally.
 
-## Temperature Setting
-
-You can optionally configure the temperature via environment variable:
-
-```bash
-TEMPERATURE=0  # More deterministic output (recommended for diagrams)
-```
-
-**Important**: Leave `TEMPERATURE` unset for models that don't support temperature settings, such as:
-- GPT-5.1 and other reasoning models
-- Some specialized models
-
-When unset, the model uses its default behavior.
-
 ## Recommendations
 
 -   **Best experience**: Use models with vision support (GPT-4o, Claude, Gemini) for image-to-diagram features

-# Offline Deployment
-
-Deploy Next AI Draw.io offline by self-hosting draw.io to replace `embed.diagrams.net`.
-
-**Note:** `NEXT_PUBLIC_DRAWIO_BASE_URL` is a **build-time** variable. Changing it requires rebuilding the Docker image.
-
-## Docker Compose Setup
-
-1. Clone the repository and define API keys in `.env`.
-2. Create `docker-compose.yml`:
-
-```yaml
-services:
-  drawio:
-    image: jgraph/drawio:latest
-    ports: ["8080:8080"]
-  next-ai-draw-io:
-    build:
-      context: .
-      args:
-        - NEXT_PUBLIC_DRAWIO_BASE_URL=http://localhost:8080
-    ports: ["3000:3000"]
-    env_file: .env
-    depends_on: [drawio]
-```
-
-3. Run `docker compose up -d` and open `http://localhost:3000`.
-
-## Configuration & Critical Warning
-
-**The `NEXT_PUBLIC_DRAWIO_BASE_URL` must be accessible from the user's browser.**
-
-| Scenario | URL Value |
-|----------|-----------|
-| Localhost | `http://localhost:8080` |
-| Remote/Server | `http://YOUR_SERVER_IP:8080` or `https://drawio.your-domain.com` |
-
-**Do NOT use** internal Docker aliases like `http://drawio:8080`; the browser cannot resolve them.
