+
+* Project Overview
+OrgTree is a web-based interface for visualizing org-mode files as interactive trees.
+
+** Goals
+- [ ] Create intuitive tree visualization
+- [X] Support file import/export
+- [ ] Enable real-time editing
+
+** Technical Stack
+*** Frontend
+- Vue.js 3 with TypeScript
+- Tailwind CSS for styling
+- Vite for build tooling
+
+*** Backend (Future)
+- Node.js with Express
+- Database for persistence
+
+* Development Phases
+** Phase 1: Core Implementation :DONE:
+Basic functionality is working.
+
+*** File Parser
+The parser handles standard org-mode syntax including:
+- Headings with multiple levels
+- TODO states
+- Tags and properties
+- Content blocks
+
+** Phase 2: Advanced Features :CURRENT:
+*** Drag and Drop
+Enable users to reorganize tree structure visually.
+
+*** Node Management
+- Add new nodes
+- Delete existing nodes
+- Modify node properties
+
+** Phase 3: Polish :FUTURE:
+*** Performance
+Optimize for large org files with hundreds of nodes.
+
+*** Accessibility
+Ensure keyboard navigation and screen reader support.
+
+* Notes
+** Implementation Details
+The current parsing approach uses regex-based extraction which works well for standard org-mode files.
+
+** Known Issues
+- Large files may cause performance problems
+- Some advanced org-mode features not yet supported
