I did this project just to help me with instalation and maintenance of my arch and so on, but feel free to use it as you wish.
git clone https://github.com/SrCrow02/Arch-initial-configuration-helper
chmod +x dev_init.sh
./dev_init.shThe code will require you to type some informations and start the init with several configurations, download important things like firewall and enable it.
This is a daily script for the security and health of your system, do it always.
