 Installation
 ------------
 
-First you have to install libSkindesignerAPI:
+Skindesigner consists of the Skindesigner Plugin itself and a shared library
+called "libSkindesignerAPI" which allows other Plugins to use the facilities of
+Skindesigner. Since these other Plugins need to have access to the library,
+the library has to be proper installed on your system. 
 
-cd <PLUGINSOURCEDIR>/libskindesignerapi
-make clean
-make install
+With a "make install" both the plugin and the library are installed on your

+the PREFIX parameter: "PREFIX=/usr make install". Default of PREFIX is

+pkg-config --cflags libskindesignerapi
