+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+

+
+       1) Use a suitable shared library mechanism for linking with the

+# kwin-style-ukui -- UKUI KWin Decoration Project
+
+## Introduction & Background
+KDE is a well-known desktop environment in the worldwide. Its window manager - KWin is also an amayzing project, which providing many cool effects, and allowding us to extend it with plugins or scripts.
+
+The ukui-kwin-style is based on the KDecoration2, which is an extensible frameworks for KWin to custom a window decoration style, such as title bar, border and shadow. The projects similar with this one are kwin-style-breeze and kwin-decoration-oxygen, etc... Breeze and Oxygen are also providing the applications style based on Qt style frameworks, infuenting most Qt applications.
+
+This project has 2 main targets:
+1. providing the decorations for normal windows, and keep the decorations suiting for ukui styles.
+2. providing the decorations for special windows (a client side decoration window), such as peony, ukui-control-center, decorating special windows with shadow and a resize handler.
+
+The difference between normal windows and special windows (csd windows) in X11 is window's motif hints atom, which is a protocol of NETWM. However, there are many arguments about client side decoration, so breeze and oxygen choose to ignore some flags of motif hints (actually not handled, motif hints only handled at kwin self), which related csd.
+
+As a developer, I'd like to stand by ssd (sever side decoration) side, but I have to meet the needs of UI designers. I have tried many ways to archives those goals, and as rebasing the rules as possible. I am still looking for the best solution, and this project may just be a step on the way. Actually I don't think I have found a good solution for resolve the arguments on csd, and I gusse it will continue a loog while.
+
+## HOW it works?
+In X Window System, there are many protocol between X client (a window) and X sever. Window Manager take over the works of X sever in current PC (In x11 platform), and handle these protocols.
+
+For now, **ICCCM** and **NETWM** is the common protocols in different X11 desktop environment. One protocol of NETWM -- **motif hints** is a protocol to control the window decoration and supported actions provided by window manager.
+
+Throughing motif hints, window can define a rules telling window manager how to decorate it, and enable/disable window interaction actions.
+
+KWin's decoration frameworks, KDecoration2, provides us the convinience access between window and window manger. It let us just need consider how to render decoration for a window. For a decoration to be painted, it can get the window handle from client() which provided by the frameworks. So, we can check the window motif hints durring rendering it. 
+
+For a csd window, the windows motif hints should be different with the normal one, this is mostly handled by gui libraries, such as Qt and GTK. In X11 platform, Qt's frameless window and GTK's csd window both change the motif hints of the window, but their hints are different, that cause a csd window seems better than frameless one. For example, csd window can resize without any hacking, and also has shadow rounded.
+
+The task is taked over by ourself. Implement a KDecoration2 plugin, and use it to handle the different window (note that some window will not handled in plugin, such as frameless window, and gtk csd window, it handled by kwin itself).
+
+If you want to learn more about kwin, the [**offical document**](https://community.kde.org/KWin) is recommend.
+
+## Build and Test
+- Dependencies (in debian):
+   - cmake
+   - extra-cmake-modules
+   - libkdecorations2-dev
+   - libqt5x11extras5-dev
+   - libkf5coreaddons-dev
+   - libkf5windowsystem-dev
+
+- Build and Install
+   - clone this project and enter into top directory
+   - mkdir build && cd build
+   - cmake ..
+   - make
+   - sudo make install
+   - ./test-csd (if use kwin-style-ukui)
+
+- Test
+   - open KDE System Settings (systemsettings5)
+   - Apperance > Application Style > Window Decoration
+   - choose UKUI as decoration and apply
+   - run a demo, which windows' motif hints is different.
+

+
+![pictrue2](screenshots/csd-window.png)
+
+![pictrue3](screenshots/window-screenshot-of-csd-window.png)
+
+## TODO
+- Basic decoration rendering. Not only be a demo.
+- Support unity border radius protocol, and handle the rounded-corner window's shadow.
+- Register an atom to _NET_SUPPORTED. Let window know if kwin-ukui-style used.
+- An implement in wayland?
