 ## 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.
+This repository contains a macOS markdown viewer application built with SwiftUI. The app allows users to open markdown files and render them with HTML preview in individual windows.
 
 ## 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]`
+- Build: `xcodebuild -project MarkdownViewer.xcodeproj -scheme MarkdownViewer -configuration Debug`
+- Clean: `xcodebuild clean -project MarkdownViewer.xcodeproj`
+- Open in Xcode: `open MarkdownViewer.xcodeproj`
 
 ## Architecture & Structure
 
-*Note: Project architecture will be documented here as the codebase develops.*
+- **MarkdownViewerApp.swift**: Main app entry point with Settings scene and File menu integration
+- **ContentView.swift**: Contains MarkdownDocumentView for displaying markdown content
+- **MarkdownRenderer.swift**: NSViewRepresentable wrapper for WKWebView with markdown-to-HTML conversion
+- **MarkdownViewer.entitlements**: App entitlements with sandbox disabled for WebView functionality
 
 ## Getting Started
 
-This is a fresh repository. When beginning development:
+1. Open the project: `open MarkdownViewer.xcodeproj`
+2. Build and run the application in Xcode (⌘R)
+3. Use File → Open Markdown File (⌘O) to open markdown files
+4. Each file opens in its own window with rendered HTML preview
 
-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
+## TODO - Feature Ideas
 
-## Notes for Future Development
+*Add new feature ideas here that can be worked on in future development sessions*
 
-- 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
