 # VNote Agent Development Guide
 
+## Setup
+
+After cloning the repository, run the init script to set up your development environment:
+* **Linux/macOS**: `bash scripts/init.sh`
+* **Windows**: `scripts\init.cmd`
+
 ## Build/Lint/Test Commands
 
 * **Build**: `mkdir build && cd build && cmake .. && cmake --build . --config Release`
-* **Run Tests**: Build tests manually by enabling `add_subdirectory(tests)` in root CMakeLists.txt
-* **Run Single Test**: `cd build && ctest -R test_task` (after building tests)
+* **Debug Build**: `cmake .. -DCMAKE_BUILD_TYPE=Debug && cmake --build . --config Debug`
+* **Run Tests**: Uncomment `add_subdirectory(tests)` in root CMakeLists.txt, rebuild, then `ctest`
+* **Run Single Test**: `ctest -R test_task` (use test name pattern matching)
+* **Format Code**: Use clang-format with provided `.clang-format` (100 char line limit, 2-space indent)
 
 ## C++ Code Style Guidelines
 
-* **Standards**: C++14, Qt 5/6 framework with MOC/UIC/RCC enabled
-* **Includes**: System includes first, then Qt includes, then local includes (see `main.cpp:1-29`)
-* **Namespaces**: Use `vnotex` namespace for all core classes
-* **Headers**: Use header guards (`#ifndef CLASSNAME_H`), forward declarations in headers
+* **Standards**: C++14, Qt 5/6 framework with CMAKE_AUTOMOC/AUTOUIC/AUTORCC enabled
+* **Includes**: Order: system includes, Qt includes, local includes (blank line between groups)
+* **Namespaces**: Use `vnotex` namespace for all core classes; `using namespace vnotex;` in .cpp files
+* **Headers**: Use header guards (`#ifndef CLASSNAME_H`), forward declarations preferred in headers
 * **Classes**: CamelCase, private inheritance for utility classes (Noncopyable pattern)
-* **Methods**: camelCase with getter prefixes (`getInst()`, `getThemeMgr()`)
-* **Members**: Prefix private members with `m_` (e.g., `m_jobj`)
-* **Singletons**: Use static instance pattern with `getInst()` method
-* **Qt Integration**: Use signals/slots, QObject inheritance, Q_OBJECT macro
-* **Memory**: Use Qt smart pointers (QScopedPointer, QSharedPointer)
-* **Config**: Access via ConfigMgr singleton, JSON-based hierarchical config
-* **Architecture**: Follow layered structure - core/ for logic, widgets/ for UI
-* **Error Handling**: Use Qt patterns and custom Exception classes
+* **Methods**: camelCase with getter prefixes (`getInst()`, `getThemeMgr()`), parameters prefixed with `p_`
+* **Members**: Prefix private members with `m_` (e.g., `m_jobj`, `m_themeMgr`)
+* **Singletons**: Use static instance pattern: `static Type &getInst() { static Type inst; return inst; }`
+* **Qt Integration**: Use signals/slots, QObject inheritance, Q_OBJECT macro for MOC
+* **Memory**: Use Qt smart pointers (QScopedPointer, QSharedPointer), not raw new/delete
+* **Config**: Access via ConfigMgr::getInst(), JSON-based hierarchical config system
+* **Architecture**: Layered structure - core/ for logic, widgets/ for UI, utils/ for helpers
+* **Error Handling**: Use custom Exception class with Exception::throwOne(), qCritical/qWarning/qInfo for logging
+* **Formatting**: 2-space indent, 100 char line limit, pointer alignment right (e.g., `int *ptr`)
 
 ## Architecture Notes
-* Core singleton: VNoteX coordinates all managers (ThemeMgr, TaskMgr, NotebookMgr, BufferMgr)  
-* Refer to .github/copilot-instructions.md for complete architecture overview
+
+* Core singleton VNoteX coordinates all managers (ThemeMgr, TaskMgr, NotebookMgr, BufferMgr)
+* ConfigMgr provides MainConfig, SessionConfig, CoreConfig, EditorConfig, WidgetConfig
+* Test framework uses Qt Test (QObject-based tests with initTestCase() and test methods)

+## Development
+
+After cloning the repository, run the initialization script to set up your development environment:
+
+**Linux/macOS:**
+```bash
+bash scripts/init.sh
+```
+
+**Windows:**
+```cmd
+scripts\init.cmd
+```
+
+This script will:
+* Initialize and update all git submodules
+* Install pre-commit hooks for automatic code formatting with clang-format
+* Set up the vtextedit submodule pre-commit hook
+
+For more development guidelines, see [AGENTS.md](AGENTS.md).
