+## Programming
+
+The name space for the library is `TUPWLib`.
+This is a change from the former version that used another name space.
+
+The source code is compatible with `.NET 6`.
+One can use the same source code for `.NET Framework 4.8` and `.NET 6`.
+The solution (`.sln`) and project (`.vbproj`) files in this repository are made for `.NET Framework 4.8`.
+If one wants to use `.NET 6` or later one just has to set up a `.NET 6` library project and import the files in the `Arrays`, `Crypto`, `Numbers` and `Statistics` folders.
