+# About:
+#   DIYfetch it the shell script template for writing fetch tool
+#   utilizing `gum join` command (https://github.com/charmbracelet/gum#join).
+#
+#   This script is written in POSIX-shell for portability
+#   feel free to switch it to any scripting language that you prefer.
+#
+# Note:
+#   When copy ANSI string from random script make sure to replace "\033" and "\e" to ""
+#   or wrap it in `$(printf '%b' "<ansi_string>")`.
