+
+## Project Overview
+
+WayCast is a Raycast-like application launcher for Linux, built with C++20 and Qt6. It scans XDG desktop entries to provide a searchable interface for launching applications on Wayland/X11.
+
+## Build System
+
+The project supports three build systems:
+
+### Primary: CMake with Ninja (Recommended)
+```bash
+# Configure and build
+make configure  # or: cmake -S . -B build -G Ninja
+make bld       # or: cmake --build build
+make run       # or: ./build/waycast
+
+# Combined: make br (build + run)
+# Full rebuild: make all (configure + build + run)
+```
+
+### Alternative: Zig Build
+```bash
+zig build run
+```
+
+### Development Environment: Nix Shell
+```bash
+nix-shell  # Sets up Qt6, CMake, Ninja, Clang, and required dependencies
+```
+
+## Architecture
+
+### Core Components
+
+- **main.cpp**: Entry point, currently configured for CLI testing of desktop entry parsing
+- **dmenu.hpp/namespace**: Desktop entry parsing using GIO/GLib to read XDG application data
+- **files.hpp/namespace**: File system utilities for scanning directories and reading files
+- **ui/Main.qml**: Qt Quick interface (currently minimal, Qt GUI code commented out in main)
+
+### Key Classes
+
+- `dmenu::DesktopEntry`: Parses .desktop files using GDesktopAppInfo, extracts app metadata (name, icon, executable, display flags)
+- `files::findFilesWithExtension()`: Recursively scans directories for files with specific extensions
+- `DEVec`: Type alias for `std::unique_ptr<std::vector<DesktopEntry>>`
+
+### Current State
+
+The application is in active development:
+- Main Qt GUI loop is commented out in main.cpp:56-64
+- Currently runs as CLI tool that prints discovered application IDs
+- Desktop entry scanning logic is functional
+- Qt QML interface exists but is not connected
+
+## Dependencies
+
+- **Qt6**: Core, Gui, Qml, Quick, QuickControls2
+- **GIO/GLib**: For XDG desktop entry parsing
+- **C++20**: Uses std::format, filesystem, and modern C++ features
+- **CMake 3.21+**: Build system
+- **Ninja**: Preferred generator
+
+## Development Notes
+
+- Qt resources are bundled via CMakeLists.txt (qt_add_qml_module)
+- Uses C++20 modules compilation flags for GCC/Clang
+- Nix shell provides complete development environment with Qt6 Wayland support
+- Built-in RPATH configuration for Linux runtime library discovery
+
+## Project Conventions
+
+- We're not using header files. Prioritize .hpp
