 Compiling
 ---------
 
-Compiling FreeCAD requires the installation of several libraries and their 
-development files such as OCCT (Open Cascade), Coin and Qt, listed in the 
-pages below. Once this is done, FreeCAD can be compiled with 
-CMake. On Windows, these libraries are bundled and offered by the 
-FreeCAD team in a convenient package. On Linux, they are usually found 
-in your distribution's repositories, and on macOS and other platforms, 
-you will usually have to compile them yourself.
