+# dotfiles
 
-My dotfiles for macOS, Arch Linux, Raspbian and Android (Termux).
+My dotfiles (configurations and settings) for shells, text editors and other terminal programs, plus a collection of scripts. Written for and work on various UNIX-like OSes, primarily for:
+
+- Arch Linux,
+- Linux Mint,
+- server Ubuntu,
+- macOS with GNU coreutils (i.e. BSDs are not supported),
+- Android with Termux.
+
+And also a legendary project that has survived for thousands of years of development.
