+### Global install option
+
+If you try the user site installation above, and have problems making
+borgmatic commands runnable on your system `PATH`, an alternate approach is to

+possibility for libary conflicts. But if you're okay with that, for instance
+on a relatively dedicated system, then a global install can work out just
+fine.
