 ## Introduction
 
-This repo contains:
+SHS Toolkit is metaproject, that contains references to CMake, PIP, QAD, CD and QGLEngine.
+* CMake - many CMake helpers and wrappers
+* PIP - Platform-Independent Primitives, C++ libraries to solve many common tasks
+* QAD - Qt for Advanced Developers, many Qt-based widgets and helpers. Also provide Qt-Designer
+  plugins.
+* CD - Control/Debug toolkit, PIP-based client-server library to simplify using coefficients
+  and track some variables tasks. Also provide QAD-based pult.
+* QGLEngine - modern Qt/OpenGL-based 3D engine with PBR materials. Also provide GUI widgets
+  to edit scene and "libassimp"-based files importer.
 
-* PIP
+Each project provide Find*.cmake file with correct dependecies. So, if you call `find_package(CD)`
+then PIP and QAD will be found.
+
+Each of there projects can be built separately, but this project help you to build all at once.
+

+After successfully install, you can use next CMake imported targets:
+
+* PIP:
   * PIP - main library
   * PIP::USB - PIUSB (libusb)
   * PIP::Console - PIScreen
