-# GitHub Pages Deployment Guide
-
-This project has been configured with automatic deployment of GitHub Pages, and users can experience the complete Gantt charting function online.
-
-## 🌐 Online visit
-
-**Demo Address**: https://nelson820125.github.io/jordium-gantt-vue3/
-
-## 🔧 Deployment Configuration
-
-### Automated deployment
-
-Projects are automatically deployed to GitHub Pages using GitHub Actions:
-
-- **Triggering condition**: Push to `main` or `master` branch
-- **Build Command**: `npm run build:pages`
-- **Deployment Directory**: `./dist`
-- **Workflows**: `.github/workflows/deploy-github-pages.yml`
-
-### Enable GitHub Pages manually
-
-1. Enter the GitHub repository settings page
-2. Find the "Pages" setting options
-3. Select "Source" as "GitHub Actions"
-4. Push code to the main branch and automatically trigger deployment
-
-## 📁 Construct the product
-
-- **Development and Construction**: `npm run build` → `dist/`
-- **GitHub Pages**: `npm run build:pages` → `dist/` (contains the correct base path)
-- **NPM package build**: `npm run build:lib` → `npm-package/dist/`
-
-## 🛠️ Local Preview
-
-```bash
-# Installation dependencies
-npm install
-
-# Start the development server
-npm run dev
-
-# Build and preview the production version
-npm run build:pages
-npm run preview
-```
-
-## 🔄 Update deployment
-
-GitHub Actions will automatically:
-
-1. Check out the code
-2. Install Node.js and dependencies
-3. Build demo application
-4. Deploy to GitHub Pages
-
-## 📝 Notes
-
-- Deployment usually takes 1-5 minutes to take effect
-- Make sure GitHub Pages is enabled in repository settings
-- Custom domain names need to be configured in the `demo/public/CNAME` file
-- Static resource paths use relative paths to ensure normal loading in the Pages environment
