As a way to get hands-on experience with C+- on a Linux machine we find 7 projects prepared after having copied the folder 'cpm' into some void directory. Their names (projects and their directories) and scopes are tut1 (for 'tutorial 1', bench mark on vector templates), tut2 (for 'tutorial 2', various integrators for the Kepler problem), chebyshev ( on functions as values, with Chebyshev-polynomials as examples), testcpm0 ( test for the basic C+- templates) alftest ( applying the asynchronous leap frog integrator on various physical systems) pala ('particle lab', classical mechanics of grains and powders), vqm2 ('visual quantum mechanics 2', non-relativistic), For each of these projects there is a directory with the same name, which, among other items, contains a Code::Blocks project file, tut1.cbp ... vqm2.cbp. For users of other project building tools, these project files, when opened with a normal text editor, will allow retrieving the information fitting their needs. Each of these project-specific directories has subdirectories include and source. The first of these contains files cpmdefinitions.h and cpmsystemdependencies.h which control the compiler and the linker. The second of these contains project specific code which is not general enough to fit in the library type source collection cpm0, ..., cpm4. All the project directories have subdirectory 'control' and a file 'cpmconfig.ini' for controling program execution. Finally, on the same level as the project directories and the 'library directories' there is a directory 'fonts', which holds the fonts-related tools of C+-. To avoid unnecessary work one should not change the relative position of the directories during work. To run the programs as they are set-up, one is best off if one has some experience with building C++ projects using the Code::Blocks IDE and knows how to find and install libraries such as glut and GL and how to make the gnu compiler understand C++20. Who is interested in running programs in multiple precision arithmetics will find hints in the C+- tutorial and in the files cpmdefinitionswrc.h, cpmsystemdependencieswrc.h, and cpmconfigwrc.ini in the directory /cpm0/doc.
