-The following setup script are provided:
-* **mac_setup.sh**: installation using brew (brew will be installed if not present).
-* **void_setup.sh**: Xbps dependencies for Void Linux.
+The script will try to recognize which system you are running,

+package manager, please consider adding support for it into the script
+and sending a patch.
