-## GitHub Repository Setup
-
-This project is already initialized as a Git repository. To push it to a private GitHub repository:
-
-### Option 1: Using GitHub CLI (Recommended)
-
-1. Install GitHub CLI if not already installed:
-   ```bash
-   # On Ubuntu/Debian
-   sudo apt install gh
-   
-   # On macOS
-   brew install gh
-   ```
-
-2. Authenticate with GitHub:
-   ```bash
-   gh auth login
-   ```
-
-3. Create a new private repository:
-   ```bash
-   gh repo create quadratic-plotter --private --source=. --remote=origin --push
-   ```
-
-### Option 2: Manual Setup
-
-1. Create a new private repository on [GitHub.com](https://github.com/new):
-   - Repository name: `quadratic-plotter` (or your preferred name)
-   - Select "Private"
-   - Do NOT initialize with README, .gitignore, or license
-
-2. Add the remote and push:
-   ```bash
-   git remote add origin https://github.com/YOUR_USERNAME/quadratic-plotter.git
-   git branch -M main
-   git push -u origin main
-   ```
-
-### Option 3: Using SSH
-
-If you prefer SSH authentication:
-
-1. Add your SSH key to GitHub
-2. Use SSH URL:
-   ```bash
-   git remote add origin git@github.com:YOUR_USERNAME/quadratic-plotter.git
-   git branch -M main
-   git push -u origin main
-   ```
-
-### Verification
-
-After pushing, verify your repository:
-```bash
-git log --oneline
-git remote -v
-git status
-```
