 # WizardMerge
 
+**Intelligent Merge Conflict Resolution**
 
 SEE ALSO: https://github.com/JohnDoe6345789/mergebot
 
+WizardMerge is a powerful tool for resolving merge conflicts using intelligent algorithms based on research from The University of Hong Kong. It combines dependency analysis at both text and LLVM-IR levels to provide smart merge suggestions.
 
+## Architecture
 
-PyQt6 + QML demo application that showcases a themed UI shell alongside simple
+WizardMerge uses a multi-frontend architecture with a high-performance C++ backend and multiple frontend options:
-merge algorithm helpers. The project ships with a theming plugin system so you
-can extend the UI palette without touching the core code.
 
-## Features
+### Backend (C++)
-- PyQt6 application bootstrapped from `wizardmerge.app`
+- **Location**: `backend/`
-- QML front-end that reads theme colors from the Python context
+- **Build System**: CMake + Ninja
-- Built-in light and dark themes plus an example warm plugin theme
+- **Package Manager**: Conan
-- Simple merge algorithm utilities in `wizardmerge.algo`
+- **Features**: Three-way merge algorithm, conflict detection, auto-resolution
-- Helper scripts for environment setup and running the app
+
+### Frontend (TypeScript/Next.js)
+- **Location**: `frontend/`
+- **Runtime**: bun
+- **Framework**: Next.js 14
+- **Features**: Web-based UI for conflict resolution
 
 ## Roadmap
-See [ROADMAP.md](ROADMAP.md) for our vision and development plan to make resolving merge conflicts easier. The roadmap covers:
+See [ROADMAP.md](ROADMAP.md) for our vision and development plan. The roadmap covers:
-- Enhanced merge algorithms (three-way merge, conflict detection)
+- Enhanced merge algorithms (three-way merge, conflict detection) ✓
 - Smart semantic merging for different file types
 - Advanced visualization and UI improvements
 - Git workflow integration
 - AI-assisted conflict resolution
 
 ## Getting Started
-1. Create a virtual environment and install dependencies:
-   ```sh
-   ./setup.sh
-   ```
 
-2. Launch the GUI (activates `.venv` automatically when present):
+### C++ Backend
-   ```sh
-   ./run_app.sh
-   ```
 
-3. To install requirements into an existing environment instead of creating a
+```sh
-   new one:
+cd backend
-   ```sh
+./build.sh
-   ./install_all_python.sh
+```
-   ```
 
-## Theming
+See [backend/README.md](backend/README.md) for details.
-Themes live under `wizardmerge/themes`. Built-ins follow the `<name>_theme.py`
-pattern. Plugin themes can be placed in `wizardmerge/themes/plugins` or in any
-folder passed to `ThemeManager(extra_plugin_paths=[Path("/path/to/themes")])`.
-Each theme module must expose a `Theme` instance named `theme` (or the
-`warm_theme` example) with a palette mapping of color keys used by the QML UI.
 
-## QML
+### TypeScript Frontend
-The UI entry point is `wizardmerge/qml/main.qml`. It binds to a `theme` context
-property injected from Python so you can use colors consistently across QML
-components. Maintain two-space indentation when updating QML files.
 
-## Algorithms
+```sh
-`wizardmerge/algo/merge.py` offers a deterministic `merge_pairs` function for
+cd frontend
-interleaving two sequences of lines and reporting their origins. The GUI can be
+bun install
-extended to call these helpers when you add inputs to the placeholder area in
+bun run dev
-the QML layout.
+```
+
+See [frontend/README.md](frontend/README.md) for details.
+
+## Research Foundation
+
+WizardMerge is based on research from The University of Hong Kong achieving:
+- 28.85% reduction in conflict resolution time
+- Merge suggestions for over 70% of code blocks affected by conflicts
+- Dependency analysis at text and LLVM-IR levels
+
+See [docs/PAPER.md](docs/PAPER.md) for the complete research paper.
