+
+## Build Commands
+
+### Basic Build
+```bash
+# Configure with CMake (release build)
+cmake -B build -j16
+
+# Build the project
+cmake --build build -j16
+
+# Install (default system location)
+cmake --build build --target install -j16
+
+# Local install (bin/lib/include in build directory)
+cmake -B build -DLOCAL=ON -j16
+```
+
+### With Tests
+```bash
+cmake -B build -DTESTS=ON -j16
+cmake --build build -j16
+cd build && ctest
+```
+
+### Build Only
+```bash
+cmake --build build -j16
+```
+
+### Run Single Test
+```bash
+# After building with TESTS=ON
+./build/tests/math/pip_math_test --gtest_filter="Vector2DTest.defaultConstructor*"
+# Or use ctest
+ctest -R math -V
+# List all tests
+ctest -N
+```
+
+### Build Options
+- `TESTS=ON` - Build tests (requires Google Test)
+- `COVERAGE=ON` - Build with coverage instrumentation
+- `ICU=ON` - Enable ICU support for string conversion
+- `STD_IOSTREAM=ON` - Enable std::iostream operators
+- `INTROSPECTION=ON` - Build with introspection support
+- `PIP_BUILD_*` - Enable/disable modules (e.g., `PIP_BUILD_CRYPT=OFF`)
+
+### Code Generation Tools
+- `pip_cmg` - Code model generator (auto-generates code from comments)
+- `pip_rc` - Resources compiler (embeds resources into C++ code)
+- `pip_tr` - Translation tool (compiles .btf translation files)
+
+### Linting & Formatting
+- **clang-format**: Run `clang-format -i <file>` or `find . -name "*.cpp" -o -name "*.h" | xargs clang-format -i`
+- **Format config**: `.clang-format` (ColumnLimit: 140, IndentWidth: 4, BraceWrapping: Attach)
+- **Includes sorting**: Enabled (CaseSensitive, SortIncludes: true)
+- **Macro blocks**: `PRIVATE_DEFINITION_START/END`, `STATIC_INITIALIZER_BEGIN/END`, `DECLARE_UNIT_CLASS_BEGIN/END`
+- **No Cursor/Copilot rules** found in this repository
+
+## Code Style Guidelines
+
+### General
+- **Language Standard**: C++11 (CMAKE_CXX_STANDARD 11)
+- **File Encoding**: UTF-8
+- **Line Endings**: Unix (LF)
+- **Column Limit**: 140 characters
+
+### Naming Conventions
+- **Classes**: `PascalCase` (e.g., `PIObject`, `PIString`)
+- **Functions/Methods**: `camelCase` (e.g., `toString()`, `isEmpty()`)
+- **Variables**: `camelCase` (e.g., `rowCount`, `isReady`)
+- **Constants**: `kPrefixCamelCase` (e.g., `kMaxSize`)
+- **Macros**: `UPPER_CASE` (e.g., `PIP_EXPORT`, `NO_COPY_CLASS`)
+- **Types**: `PascalCase` with `p` prefix for internal/private (e.g., `PIString_p.h`)
+
+### File Naming
+- Headers: `pi<name>.h` (e.g., `piobject.h`, `pistring.h`)
+- Private headers: `pi<name>_p.h` (e.g., `piobject_p.h`)
+- Test files: `test<name>.cpp` (e.g., `testpivector2d.cpp`)
+
+### Comments & Documentation
+- Use Doxygen-style comments for all public APIs
+- Include `\~english` and `\~russian` translations
+- Group related classes/modules with `//! \defgroup`
+- Use `\ingroup` to assign files to groups
+- Example:
+  ```cpp
+  //! \file piobject.h
+  //! \ingroup Core
+  //! \~\brief
+  //! \~english Base object
+  //! \~russian Базовый класс
+  ```
+
+### Includes
+- Order: System headers → PIP headers → Local headers
+- Sort alphabetically within groups
+- Use `#pragma once` or include guards
+- PIP includes use `#include "pi<name>.h"`
+
+### Formatting (clang-format)
+- **Indentation**: 4 spaces (no tabs for code)
+- **Braces**: Attach style (`if (x) {`)
+- **Pointers/References**: `Type* ptr`, `Type& ref`
+- **Templates**: Always break before `>` in nested templates
+- **Empty Lines**: Max 2 consecutive empty lines
+- **Namespace**: No indentation (`Namespace { ... }`)
+
+### Error Handling
+- Use `PIString` for error messages
+- Return bool for success/failure
+- Use `assert()` for debug-only checks
+- Avoid exceptions (RTTI disabled in some builds)
+
+### Memory Management
+- Prefer stack allocation
+- Use `NO_COPY_CLASS(MyClass)` to disable copy
+- Implement proper move semantics when needed
+- Use `std::unique_ptr`/`std::shared_ptr` sparingly
+
+### Macros
+- PIMETA(...) - Add metadata for code model generator
+- PIP_EXPORT - Export/import symbols for DLLs
+- NO_COPY_CLASS - Disable copy constructor and operator=
+- PRIVATE_DECLARATION - Private implementation macro
+
+## Testing
+- Framework: Google Test (fetched automatically when TESTS=ON)
+- Test files: `tests/<module>/test<name>.cpp`
+- Use `pip_test(module)` macro in `tests/CMakeLists.txt`
+- Test discovery via `gtest_discover_tests()`
+
+### Running Tests
+```bash
+# Run all tests
+ctest
+
+# Run specific test suite
+ctest -R math -V
+
+# List all available tests
+ctest -N
+
+# Run single test with gtest filter
+./build/tests/math/pip_math_test --gtest_filter="Vector2DTest.defaultConstructor*"
+```
+
+## Module Structure
+```
