 ## Sandboxing
 
-### macOS Seatbelt
-
-On macOS, `qwen` uses Seatbelt (`sandbox-exec`) under a `permissive-open` profile (see `packages/cli/src/utils/sandbox-macos-permissive-open.sb`) that restricts writes to the project folder but otherwise allows all other operations and outbound network traffic ("open") by default. You can switch to a `restrictive-closed` profile (see `packages/cli/src/utils/sandbox-macos-restrictive-closed.sb`) that declines all operations and outbound network traffic ("closed") by default by setting `SEATBELT_PROFILE=restrictive-closed` in your environment or `.env` file. Available built-in profiles are `{permissive,restrictive}-{open,closed,proxied}` (see below for proxied networking). You can also switch to a custom profile `SEATBELT_PROFILE=<profile>` if you also create a file `.qwen/sandbox-macos-<profile>.sb` under your project settings directory `.qwen`.
-
-### Container-based Sandboxing (All Platforms)
-
-For stronger container-based sandboxing on macOS or other platforms, you can set `GEMINI_SANDBOX=true|docker|podman|<command>` in your environment or `.env` file. The specified command (or if `true` then either `docker` or `podman`) must be installed on the host machine. Once enabled, `npm run build:all` will build a minimal container ("sandbox") image and `npm start` will launch inside a fresh instance of that container. The first build can take 20-30s (mostly due to downloading of the base image) but after that both build and start overhead should be minimal. Default builds (`npm run build`) will not rebuild the sandbox.
-
-Container-based sandboxing mounts the project directory (and system temp directory) with read-write access and is started/stopped/removed automatically as you start/stop Gemini CLI. Files created within the sandbox should be automatically mapped to your user/group on host machine. You can easily specify additional mounts, ports, or environment variables by setting `SANDBOX_{MOUNTS,PORTS,ENV}` as needed. You can also fully customize the sandbox for your projects by creating the files `.qwen/sandbox.Dockerfile` and/or `.qwen/sandbox.bashrc` under your project settings directory (`.qwen`) and running `qwen` with `BUILD_SANDBOX=1` to trigger building of your custom sandbox.
-
-#### Proxied Networking
-
-All sandboxing methods, including macOS Seatbelt using `*-proxied` profiles, support restricting outbound network traffic through a custom proxy server that can be specified as `GEMINI_SANDBOX_PROXY_COMMAND=<command>`, where `<command>` must start a proxy server that listens on `:::8877` for relevant requests. See `docs/examples/proxy-script.md` for a minimal proxy that only allows `HTTPS` connections to `example.com:443` (e.g. `curl https://example.com`) and declines all other requests. The proxy is started and stopped automatically alongside the sandbox.

-## VS Code Extension
-
-In addition to the CLI tool, Qwen Code also provides a **VS Code extension** that brings AI-powered coding assistance directly into your editor with features like file system operations, native diffing, interactive chat, and more.
-
-> 📦 The extension is currently in development. For installation, features, and development guide, see the [VS Code Extension README](./packages/vscode-ide-companion/README.md).
-
 ## Quick Start
 
 ```bash
-# Start Qwen Code
+# Start Qwen Code (interactive)
 qwen
 
-# Example commands
-> Explain this codebase structure
-> Help me refactor this function
-> Generate unit tests for this module
+# Then, in the session:
+/help
+/auth
 ```
 
-### Session Management
+On first use, you'll be prompted to sign in. You can run `/auth` anytime to switch authentication methods.
 
-Control your token usage with configurable session limits to optimize costs and performance.
+Example prompts:
 
-#### Configure Session Token Limit
-
-Create or edit `.qwen/settings.json` in your home directory:
-
-```json
-{
-  "sessionTokenLimit": 32000
-}
+```text
+What does this project do?
+Explain the codebase structure.
+Help me refactor this function.
+Generate unit tests for this module.
 ```
 
-#### Session Commands
-
-- **`/compress`** - Compress conversation history to continue within token limits
-- **`/clear`** - Clear all conversation history and start fresh
-- **`/stats`** - Check current token usage and limits
-
-> 📝 **Note**: Session token limit applies to a single conversation, not cumulative API calls.
-
-### Vision Model Configuration
-
-Qwen Code includes intelligent vision model auto-switching that detects images in your input and can automatically switch to vision-capable models for multimodal analysis. **This feature is enabled by default** - when you include images in your queries, you'll see a dialog asking how you'd like to handle the vision model switch.
-
-#### Skip the Switch Dialog (Optional)
-
-If you don't want to see the interactive dialog each time, configure the default behavior in your `.qwen/settings.json`:
-
-```json
-{
-  "experimental": {
-    "vlmSwitchMode": "once"
-  }
-}
-```
-
-**Available modes:**
-
-- **`"once"`** - Switch to vision model for this query only, then revert
-- **`"session"`** - Switch to vision model for the entire session
-- **`"persist"`** - Continue with current model (no switching)
-- **Not set** - Show interactive dialog each time (default)
-
-#### Command Line Override
-
-You can also set the behavior via command line:
-
-```bash
-# Switch once per query
-qwen --vlm-switch-mode once
-
-# Switch for entire session
-qwen --vlm-switch-mode session
-
-# Never switch automatically
-qwen --vlm-switch-mode persist
-```
-
-#### Disable Vision Models (Optional)
-
-To completely disable vision model support, add to your `.qwen/settings.json`:
-
-```json
-{
-  "experimental": {
-    "visionModelPreview": false
-  }
-}
-```
-
-> 💡 **Tip**: In YOLO mode (`--yolo`), vision switching happens automatically without prompts when images are detected.
-
-### Authorization
-
-Choose your preferred authentication method based on your needs:
-
-#### 1. Qwen OAuth (🚀 Recommended - Start in 30 seconds)
-
-The easiest way to get started - completely free with generous quotas:
-
-```bash
-# Just run this command and follow the browser authentication
-qwen
-```
-
-**What happens:**
-
-1. **Instant Setup**: CLI opens your browser automatically
-2. **One-Click Login**: Authenticate with your qwen.ai account
-3. **Automatic Management**: Credentials cached locally for future use
-4. **No Configuration**: Zero setup required - just start coding!
-
-**Free Tier Benefits:**
-
-- ✅ **2,000 requests/day** (no token counting needed)
-- ✅ **60 requests/minute** rate limit
-- ✅ **Automatic credential refresh**
-- ✅ **Zero cost** for individual users
-- ℹ️ **Note**: Model fallback may occur to maintain service quality
-
-#### 2. OpenAI-Compatible API
-
-Use API keys for OpenAI or other compatible providers:
-
-**Configuration Methods:**
-
-1. **Environment Variables**
-
-   ```bash
-   export OPENAI_API_KEY="your_api_key_here"
-   export OPENAI_BASE_URL="your_api_endpoint"
-   export OPENAI_MODEL="your_model_choice"
-   ```
-
-2. **Project `.env` File**
-   Create a `.env` file in your project root:
-   ```env
-   OPENAI_API_KEY=your_api_key_here
-   OPENAI_BASE_URL=your_api_endpoint
-   OPENAI_MODEL=your_model_choice
-   ```

-## Usage Examples
+## Usage
 
-### 🔍 Explore Codebases
+As an open-source terminal agent, you can use Qwen Code in four primary ways:
+
+1. Interactive mode (terminal UI)
+2. Headless mode (scripts, CI)
+3. IDE integration (VS Code, Zed)
+4. TypeScript SDK
+
+#### Interactive mode
 
 ```bash
 cd your-project/
 qwen
-
-# Architecture analysis
-> Describe the main pieces of this system's architecture
-> What are the key dependencies and how do they interact?
-> Find all API endpoints and their authentication methods
 ```
 
-### 💻 Code Development
+Run `qwen` in your project folder to launch the interactive terminal UI. Use `@` to reference local files (for example `@src/main.ts`).
+
+#### Headless mode
 
 ```bash
-# Refactoring
-> Refactor this function to improve readability and performance
-> Convert this class to use dependency injection
-> Split this large module into smaller, focused components
-
-# Code generation
-> Create a REST API endpoint for user management
-> Generate unit tests for the authentication module
-> Add error handling to all database operations
+cd your-project/
+qwen -p "your question"
 ```
 
-### 🔄 Automate Workflows
+Use `-p` to run Qwen Code without the interactive UI—ideal for scripts, automation, and CI/CD. Learn more: [Headless mode](https://qwenlm.github.io/qwen-code-docs/en/users/features/headless).
 
-```bash
-# Git automation
-> Analyze git commits from the last 7 days, grouped by feature
-> Create a changelog from recent commits
-> Find all TODO comments and create GitHub issues
+#### IDE integration
 
-# File operations
-> Convert all images in this directory to PNG format
-> Rename all test files to follow the *.test.ts pattern
-> Find and remove all console.log statements
-```
+Use Qwen Code inside your editor (VS Code and Zed):

+# Language Settings
+
+Qwen Code supports multiple languages for both the user interface and LLM responses.
+
+## Overview
+
+Two separate language settings control different aspects of Qwen Code:
+
+| Setting            | What it controls                                   | Where stored                 |
+| ------------------ | -------------------------------------------------- | ---------------------------- |
+| `/language ui`     | Terminal UI text (menus, system messages, prompts) | `~/.qwen/settings.json`      |
+| `/language output` | Language the AI responds in                        | `~/.qwen/output-language.md` |
+
+## UI Language
+
+### Setting the UI Language
+
+Use the `/language ui` command:
+
+```bash
+/language ui zh-CN    # Chinese
+/language ui en-US    # English
+/language ui ru-RU    # Russian
+/language ui de-DE    # German
+```
+
+Aliases are also supported:
+
+```bash
+/language ui zh       # Chinese
+/language ui en       # English
+/language ui ru       # Russian
+/language ui de       # German
+```
+
+### Auto-detection
+
+On first startup, Qwen Code detects your system locale and sets the UI language automatically.
+
+Detection priority:
+
+1. `QWEN_CODE_LANG` environment variable
+2. `LANG` environment variable
+3. System locale via JavaScript Intl API
+4. Default: English
+
+## LLM Output Language
+
+The LLM output language controls what language the AI assistant responds in, regardless of what language you type your questions in.
+
+### How It Works
+
+The LLM output language is controlled by a rule file at `~/.qwen/output-language.md`. This file is automatically included in the LLM's context during startup, instructing it to respond in the specified language.
+
+### Auto-detection
+
+On first startup, if no `output-language.md` file exists, Qwen Code automatically creates one based on your system locale. For example:
+
+- System locale `zh` creates a rule for Chinese responses
+- System locale `en` creates a rule for English responses
+- System locale `ru` creates a rule for Russian responses
+- System locale `de` creates a rule for German responses
+
+### Manual Setting
+
+Use `/language output <language>` to change:
+
+```bash
+/language output Chinese
+/language output English
+/language output Japanese
+/language output German
+```
+
+Any language name works. The LLM will be instructed to respond in that language.
+
+### File Location
+
+```
+~/.qwen/output-language.md
+```
+
+## Configuration
+
+### Via Settings Dialog
+
+1. Run `/settings`
+2. Find "Language" under General
+3. Select your preferred UI language
+
+### Via Environment Variable
+
+```bash
+export QWEN_CODE_LANG=zh
+```
+
+This sets both the UI language detection and the LLM output language detection on first startup.
+
+## Custom Language Packs
+
+For UI translations, you can create custom language packs in `~/.qwen/locales/`:
+
+- Example: `~/.qwen/locales/es.js` for Spanish
+- Example: `~/.qwen/locales/fr.js` for French
+
+User directory takes precedence over built-in translations.
+
+### Language Pack Format
+
+```javascript
+// ~/.qwen/locales/es.js
+export default {
+  Hello: 'Hola',
+  Settings: 'Configuracion',
+  // ... more translations
+};
+```
+
+## Related Commands
+
+- `/language` - Show current language settings
+- `/language ui [lang]` - Set UI language
+- `/language output <language>` - Set LLM output language
+- `/settings` - Open settings dialog
