+# Python
+
+It was programmed with 3.10.4. And I used some 3.10 Python expression. Thus you might get problems with older Python versions. 
+
+# C++
+
+It works without compiling the C++ modules. However it is 10x slower.   
+You need to modify the Makefile in the C++ directory to your Python installation.  
+In addition yoir Python installation needs the PyBind11 package installed. You might want to perform a  
+pip install pybind11  
+The Makefile uses clang as a compiler. If you want something else then you need to change the Makefile.
