+Compiler compatibility
+======================
 
 In order to offer a simple user interface and to allow for maximal reusability
-and extensibility, Fortuno uses object-oriented Fortran constructs extensively.
-Unfortunately, this is challenging for some older Fortran compilers. The
-following table gives an overview over the compilers which were successfully
-tested for building Fortuno. Make sure to use those compilers or any newer
-versions of them.
+and extensibility, Fortuno uses modern Fortran constructs extensively. Building
+Fortuno requires a compiler with Fortran 2018 support. The following table gives
+an overview over the compilers which were successfully tested for building
+Fortuno. We recommend to use those compilers or any newer versions of them.
