🚀 Getting Started

Local Development

1. Clone the repository

   git clone https://github.com/yourusername/Reinforcement-Learning.git
   cd Reinforcement-Learning

2. Open in browser Simply open index.html in your web browser. No build process required!

   Or use a local server:

   # Python
   python -m http.server 8000
   
   # Node.js
   npx serve
   
   # VS Code
   # Use "Live Server" extension

3. Navigate to: http://localhost:8000

🌐 Deploying to GitHub Pages

Option 1: GitHub Settings (Easiest)

1. Push your code to GitHub

   git add .
   git commit -m "Initial commit: RL Journey web app"
   git branch -M main
   git remote add origin https://github.com/yourusername/Reinforcement-Learning.git
   git push -u origin main

2. Enable GitHub Pages

   • Go to your repository on GitHub
   • Click "Settings" → "Pages"
   • Under "Source", select "main" branch and "/" root
   • Click "Save"

3. Access your site

   • Your site will be live at: https://yourusername.github.io/Reinforcement-Learning/
   • It may take a few minutes to deploy

Option 2: GitHub Actions (Advanced)

Create .github/workflows/deploy.yml:

name: Deploy to GitHub Pages

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./
