+## 三、应用与服务
+
+应用与服务模块提供了平台级的配置和管理功能，帮助你连接外部 AI 服务、集成第三方工具，并管理平台扩展。
+
+![应用与服务](/img/user-guide/feature-entry/app-service.png)
+
+点击左侧导航栏中的"应用与服务"图标，进入应用与服务页面。
+
+### 核心入口
+
+应用与服务页面中的主要功能包括：
+
+| 编号 | 功能名称 | 作用 |
+|---|---|---|
+| ① | 算力 Compute | 配置 AI 模型供应商和 API Key，如 OpenAI、阿里云、DeepSeek 等 |
+| ② | MCP 服务 MCP Services | 管理外部工具和服务集成，如 Chrome DevTools、文件系统等 |
+| ③ | 插件市场 Marketplace | 浏览和安装平台扩展插件，扩展智能体的能力范围 |
+
+### 配置流程
+
+#### 1. 配置算力服务
+
+首次使用 DesireCore 时，需要至少配置一个算力服务才能让智能体正常工作：
+
+1. 进入「应用与服务」→「算力」
+2. 点击「添加供应商」或「配置」
+3. 选择模型供应商（如 OpenAI、阿里云、DeepSeek 等）
+4. 填入 API Key 并保存
+5. 在智能体对话中选择对应模型即可使用
+
+> 💡 建议同时配置多个供应商，这样当一个服务不可用时可以自动切换。
+
+#### 2. 管理 MCP 服务
+
+MCP（Model Context Protocol）服务允许智能体连接和使用外部工具：
+
+1. 进入「应用与服务」→「MCP 服务」
+2. 查看已连接的 MCP 服务列表
+3. 可以启用或禁用特定的 MCP 服务
+4. 新增 MCP 服务需要提供配置信息
+
+#### 3. 浏览插件市场
+
+插件市场提供了多种扩展功能：
+
+| 类型 | 说明 |
+|---|---|
+| 文档处理 | 支持 Word、PDF、Excel、PPT 等文档的生成和解析 |
+| 图片生成 | 支持文生图、图片编辑等 AI 绘画功能 |
+| 语音合成 | 支持文字转语音，多种音色可选 |
+| 视频生成 | 支持文生视频、图片转视频等 |
+| 邮件管理 | 支持多邮箱收发、规则配置等 |
+
+### 常见操作路径
+
+| 目标 | 操作路径 |
+|------|---------|
+| 添加模型供应商 | 应用与服务 → 算力 → 添加供应商 → 填入 Key |
+| 启用 MCP 工具 | 应用与服务 → MCP 服务 → 启用所需工具 |
+| 安装插件 | 应用与服务 → 插件市场 → 搜索 → 安装 |
+| 切换默认模型 | 应用与服务 → 算力 → 选择供应商 → 设为默认 |
+
+### 新手建议
+
+初次使用时，建议按以下优先级配置：
+
+1. **先配置算力** — 至少添加一个 AI 模型供应商，这是使用智能体的前提
+2. **再浏览 MCP 服务** — 了解有哪些外部工具可以增强智能体的能力
+3. **最后探索插件市场** — 根据实际需求安装扩展插件
+
+> ⚠️ 算力配置涉及 API Key 等敏感信息，请妥善保管，不要泄露给他人。

+## 4. Applications & Services
+
+The Applications & Services module provides platform-level configuration and management features, helping you connect external AI services, integrate third-party tools, and manage platform extensions.
+
+![Applications & Services](/img/user-guide/feature-entry/app-service.png)
+
+Click the "Applications & Services" icon in the left navigation bar to enter the Applications & Services page.
+
+### Core Entry Points
+
+The main functions on the Applications & Services page include:
+
+| No. | Function | Purpose |
+|---|---|---|
+| ① | Compute | Configure AI model providers and API keys, such as OpenAI, Alibaba Cloud, DeepSeek, etc. |
+| ② | MCP Services | Manage external tool and service integrations, such as Chrome DevTools, file systems, etc. |
+| ③ | Marketplace | Browse and install platform extension plugins to expand agent capabilities |
+
+### Configuration Flow
+
+#### 1. Configure Compute Services
+
+When using DesireCore for the first time, you need to configure at least one compute service for agents to work properly:
+
+1. Navigate to "Applications & Services" → "Compute"
+2. Click "Add Provider" or "Configure"
+3. Select a model provider (e.g., OpenAI, Alibaba Cloud, DeepSeek, etc.)
+4. Enter your API key and save
+5. Select the corresponding model in agent conversations to start using it
+
+> 💡 We recommend configuring multiple providers so the system can automatically switch when one service is unavailable.
+
+#### 2. Manage MCP Services
+
+MCP (Model Context Protocol) services allow agents to connect to and use external tools:
+
+1. Navigate to "Applications & Services" → "MCP Services"
+2. View the list of connected MCP services
+3. Enable or disable specific MCP services as needed
+4. Adding new MCP services requires providing configuration details
+
+#### 3. Browse the Marketplace
+
+The marketplace provides various extension features:
+
+| Type | Description |
+|---|---|
+| Document Processing | Support for generating and parsing Word, PDF, Excel, PPT, and other document formats |
+| Image Generation | Support for text-to-image, image editing, and other AI drawing features |
+| Text-to-Speech | Support for converting text to speech with multiple voice options |
+| Video Generation | Support for text-to-video, image-to-video, and other features |
+| Email Management | Support for multi-mailbox send/receive, rule configuration, and more |
+
+### Common Navigation Paths
+
+| Goal | Navigation Path |
+|------|----------------|
+| Add a model provider | Applications & Services → Compute → Add Provider → Enter Key |
+| Enable MCP tools | Applications & Services → MCP Services → Enable desired tools |
+| Install a plugin | Applications & Services → Marketplace → Search → Install |
+| Switch default model | Applications & Services → Compute → Select Provider → Set as Default |
+
+### Tips for Beginners
+
+When using for the first time, we recommend configuring in the following priority order:
+
+1. **Configure compute first** — Add at least one AI model provider, which is a prerequisite for using agents
+2. **Then browse MCP services** — Understand what external tools are available to enhance agent capabilities
+3. **Finally explore the marketplace** — Install extension plugins based on your actual needs
+
+> ⚠️ Compute configuration involves sensitive information such as API keys. Please keep them secure and do not share them with others.
