# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
This is a new repository (`md.ai`) that appears to be related to AI/ML development based on the repository name and location structure.
## Development Commands
*Note: This repository is currently empty. Update this section as build tools, package managers, and testing frameworks are added.*
Common commands to add:
- Build: `[to be determined based on chosen framework]`
- Test: `[to be determined based on chosen testing framework]`
- Lint: `[to be determined based on chosen linting tools]`
- Dev server: `[to be determined based on chosen development setup]`
## Architecture & Structure
*Note: Project architecture will be documented here as the codebase develops.*
## Getting Started
This is a fresh repository. When beginning development:
1. Choose and set up the appropriate framework/language stack
2. Add package.json (for Node.js) or equivalent dependency management files
3. Set up testing framework and basic project structure
4. Update this CLAUDE.md with specific commands and architecture details
## Notes for Future Development
- Update the "Development Commands" section once build tools are configured
- Document the chosen architecture and key design patterns
- Add any project-specific conventions or guidelines

# Markdown Viewer Test
This is a **sample markdown file** to test the Markdown Viewer app.
## Features Supported
- **Bold text**
- *Italic text*
- `Inline code`
- [Links](https://example.com)
### Code Example
Here's some `inline code` in a paragraph.
## Lists
Basic text formatting works great with this viewer.
### Additional Notes
The app uses WebKit to render the markdown as HTML with custom CSS styling for a clean, readable appearance.
