-#### Quick Setup for Coding Plan
-
-When you select the OpenAI-compatible option in the CLI, enter these values:
-
-- **API key**: `sk-sp-xxxxx`
-- **Base URL**: `https://coding.dashscope.aliyuncs.com/v1`

-#### Configure via Environment Variables
-
-Set these environment variables to use Coding Plan:
-
-```bash
-export OPENAI_API_KEY="your-coding-plan-api-key"  # Format: sk-sp-xxxxx
-export OPENAI_BASE_URL="https://coding.dashscope.aliyuncs.com/v1"

The more relevant and precise your context files are, the better the AI can assist you. Project-specific context files are highly encouraged to establish conventions and context.

+- **Hierarchical Loading and Precedence:** The CLI implements a sophisticated hierarchical memory system by loading context files (e.g., `QWEN.md`) from several locations. Content from files lower in this list (more specific) typically overrides or supplements content from files higher up (more general). The exact concatenation order and final context can be inspected using the `/memory show` command. The typical loading order is:
   1. **Global Context File:**
      - Location: `~/.qwen/<configured-context-filename>` (e.g., `~/.qwen/QWEN.md` in your user home directory).
      - Scope: Provides default instructions for all your projects.
   2. **Project Root & Ancestors Context Files:**
      - Location: The CLI searches for the configured context file in the current working directory and then in each parent directory up to either the project root (identified by a `.git` folder) or your home directory.
      - Scope: Provides context relevant to the entire project or a significant portion of it.
+  3. **Sub-directory Context Files (Contextual/Local):**
+     - Location: The CLI also scans for the configured context file in subdirectories _below_ the current working directory (respecting common ignore patterns like `node_modules`, `.git`, etc.). The breadth of this search is limited to 200 directories by default, but can be configured with the `context.discoveryMaxDirs` setting in your `settings.json` file.
+     - Scope: Allows for highly specific instructions relevant to a particular component, module, or subsection of your project.
 - **Concatenation & UI Indication:** The contents of all found context files are concatenated (with separators indicating their origin and path) and provided as part of the system prompt. The CLI footer displays the count of loaded context files, giving you a quick visual cue about the active instructional context.
 - **Importing Content:** You can modularize your context files by importing other Markdown files using the `@path/to/file.md` syntax. For more details, see the [Memory Import Processor documentation](../configuration/memory).

+# Qwen Code Insights Page
+
+A React-based visualization dashboard for displaying coding activity insights and statistics.
+
+## Development
+
+This application consists of two parts:
+
+1. **Backend (Express Server)**: Serves API endpoints and processes chat history data
+2. **Frontend (Vite + React)**: Development server with HMR
+
+### Running in Development Mode
+
+You need to run both the backend and frontend servers:
+
+**Terminal 1 - Backend Server (Port 3001):**
+
+```bash
+pnpm dev:server
+```
+
+**Terminal 2 - Frontend Dev Server (Port 3000):**
+
+```bash
+pnpm dev
+```
+
+Then open <http://localhost:3000> in your browser.
+
+The Vite dev server will proxy `/api` requests to the backend server at port 3001.
+
+### Building for Production
+
+```bash
+pnpm build
+```
+
+This compiles TypeScript and builds the React application. The output will be in the `dist/` directory.
+
+In production, the Express server serves both the static files and API endpoints from a single port.
+
+## Architecture
+
+- **Frontend**: React + TypeScript + Vite + Chart.js
+- **Backend**: Express + Node.js
+- **Data Source**: JSONL chat history files from `~/.qwen/projects/*/chats/`
+
+## Original Vite Template Info
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+]);
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x';
+import reactDom from 'eslint-plugin-react-dom';
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+]);
+```
