+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a CMake-based build system for creating a statically linked version of CRIU (Checkpoint/Restore In Userspace) along with all its dependencies. The project builds CRIU v4.1 with all necessary libraries statically compiled to produce a self-contained binary and libcriu.o object file.
+
+## Build Commands
+
+### Configure the build
+```bash
+cmake --preset static-release
+```
+
+### Build the project
+```bash
+cmake --build --preset static-release
+```
+
+### Install or package
+```bash
+# Install directly
+sudo cmake --install build
+
+# Create package
+cpack --config build/CPackConfig.cmake --verbose -B dist -G STGZ
+```
+
+### Alternative presets
+- `static-debug` - Debug build with debug symbols
+- `static-release` - Release build (default, optimized)
+
+## Architecture
+
+### Build System Structure
+
+The project uses a sophisticated CMake build system that:
+
+1. **External Dependencies**: Downloads and builds all CRIU dependencies from source as static libraries:
+   - Protocol Buffers (protobuf & protobuf-c)
+   - Network libraries (libnet, libnl, libmnl, libnftnl, libnftables)
+   - System libraries (libcap, libaio, zlib, util-linux uuid, libintl)
+
+2. **Dependency Management**: Each dependency is managed via individual CMake files in `dependencies/` directory, using the `register_dependency()` macro from `macros/dependencies.cmake`
+
+3. **CRIU Integration**: The main CRIU build is handled as an ExternalProject that:
+   - Downloads CRIU source code
+   - Applies patches from `patch/` directory for static building
+   - Compiles with all dependencies statically linked
+   - Includes CUDA plugin compilation
+
+### Key Components
+
+- **CMakeLists.txt**: Main build configuration, sets up all dependencies and CRIU build
+- **CMakePresets.json**: Defines build presets for different configurations  
+- **dependencies/*.cmake**: Individual dependency build configurations
+- **macros/dependencies.cmake**: Macro for registering dependencies with license tracking
+- **patch/**: Contains patches applied to CRIU for static building support
+- **jreleaser.yml**: Release configuration for GitHub releases
+
+### Build Process Flow
+
+1. Configure phase downloads and builds all static dependencies in order
+2. CRIU source is downloaded and patched for static plugin support
+3. CRIU is built with custom CFLAGS/LDFLAGS pointing to static dependencies
+4. Final artifacts are installed: `criu` binary, `libcriu.o` object file, headers, and CUDA plugin
+
+### Static Plugin Architecture
+
+The build enables static plugins (STATIC_PLUGINS=y) and specifically compiles the CUDA plugin statically into the main binary rather than as a shared library, controlled by patches in `patch/criu-static-plugin.patch`.
+
+### License Management
+
+The build system automatically tracks all dependency licenses and consolidates them into `THIRD-PARTY-LICENSES.txt` for distribution compliance.
