- Customize the theme in `docs/overrides/`

## Features Preserved

Your custom code has been preserved in:

- `hooks/` - Custom build hooks
- `assets/` - Images and static files
- `javascripts/` - Custom JavaScript
- `overrides/` - Theme overrides
- `stylesheets/` - Custom CSS
- `blog/` - Blog content

## Next Steps

# Create a simple getting-started.md
cat > "$DOCS_DIR/getting-started.md" << 'EOF'
# Getting Started

Welcome to your fresh MkDocs Material site!

## Adding Content

Create new markdown files in the `docs/` directory:

```bash
docs/
├── index.md          # Homepage
├── getting-started.md # This page
├── page1.md          # Your content
└── page2.md          # More content
```

## Configuring Navigation

Edit `mkdocs.yml` to add navigation:

```yaml
nav:
  - Home: index.md
  - Getting Started: getting-started.md
  - Your Section:
    - Page 1: page1.md
    - Page 2: page2.md
```

## Using the Blog

The blog plugin is already configured. Add posts in `docs/blog/posts/`:

```markdown
---
date: 2024-01-01
categories:
  - News
---

# Your Blog Post Title

Post content here...
```

## Customization

- Theme overrides: `docs/overrides/`
- Custom CSS: `docs/stylesheets/`
- Custom JS: `docs/javascripts/`
