-### 2. Install Dependencies
-
-```bash
-npm install
-cd frontend && npm install
-```
-
-### 3. Build and Start

-## Features
-
-### Frontend Features
-
- **Dashboard**: View high priority bids and today's bids
- **Date Filtering**:
- - Click "3天" or "7天" buttons to filter bids from the last 3 or 7 days
- - The filter only limits the start date, showing all data from the selected start date onwards (including data newer than the end date)
- **Keyword Filtering**: Filter bids by keywords (saved in localStorage)
- **All Bids**: View all bids with pagination and source filtering
- **Keyword Management**: Add and delete keywords with weight-based priority
-
-### Backend Features
-
- **Multi-Source Crawling**: Crawls bidding information from multiple sources:
- - ChdtpCrawler
- - ChngCrawler
- - SzecpCrawler
- - CdtCrawler
- - EpsCrawler
- - CnncecpCrawler
- - CgnpcCrawler
- - CeicCrawler
- - EspicCrawler
- - PowerbeijingCrawler
- **Automatic Retry**: If a crawler returns 0 items, it will be retried after all crawlers complete
- **Proxy Support**: Configurable proxy settings via environment variables
- **Scheduled Tasks**: Automatic crawling at scheduled intervals
-
-### Environment Variables
-
-```env
-# Database
-DATABASE_TYPE=postgres
-DATABASE_HOST=localhost
-DATABASE_PORT=5432
-DATABASE_USERNAME=your_username
-DATABASE_PASSWORD=your_password
-DATABASE_NAME=bidding
-DATABASE_SYNCHRONIZE=true
-
-# Proxy (optional)
+# 代理配置（可选）

+OPENAI_API_KEY=your_openai_api_key
 ```

-## Initial Setup
+### 3. 安装依赖

-The system will automatically initialize with the preset keywords: "山东", "海", "建设", "工程", "采购". You can manage these and view crawled bidding information at http://localhost:3000.
+```bash
+# 安装后端依赖
+npm install
+
+# 安装前端依赖
+cd frontend && npm install
+```
+
+### 4. 运行项目

+## About
+
+This is the official Wails Vue-TS template.
+
+You can configure the project by editing `wails.json`. More information about the project settings can be found
+here: https://wails.io/docs/reference/project-config
+
+## Live Development
+
+To run in live development mode, run `wails dev` in the project directory. This will run a Vite development
+server that will provide very fast hot reload of your frontend changes. If you want to develop in a browser
+and have access to your Go methods, there is also a dev server that runs on http://localhost:34115. Connect
+to this in your browser, and you can call your Go code from devtools.
+
+## Building
+
+To build a redistributable, production mode package, use `wails build`.

+# Vue 3 + TypeScript + Vite
+
+This template should help get you started developing with Vue 3 and TypeScript in Vite. The template uses Vue
+3 `<script setup>` SFCs, check out
+the [script setup docs](https://v3.vuejs.org/api/sfc-script-setup.html#sfc-script-setup) to learn more.
+
+## Recommended IDE Setup
+
+- [VS Code](https://code.visualstudio.com/) + [Volar](https://marketplace.visualstudio.com/items?itemName=Vue.volar)
+
+## Type Support For `.vue` Imports in TS
+
+Since TypeScript cannot handle type information for `.vue` imports, they are shimmed to be a generic Vue component type
+by default. In most cases this is fine if you don't really care about component prop types outside of templates.
+However, if you wish to get actual prop types in `.vue` imports (for example to get props validation when using
+manual `h(...)` calls), you can enable Volar's Take Over mode by following these steps:
+
+1. Run `Extensions: Show Built-in Extensions` from VS Code's command palette, look
+   for `TypeScript and JavaScript Language Features`, then right click and select `Disable (Workspace)`. By default,
+   Take Over mode will enable itself if the default TypeScript extension is disabled.
+2. Reload the VS Code window by running `Developer: Reload Window` from the command palette.
+
+You can learn more about Take Over mode [here](https://github.com/johnsoncodehk/volar/discussions/471).
