## I made this tutorial with <Debian>
## <Docker>/debian
## I link to my sources but I do condense some commands and steps
dick@hardpillD:~$uname -a
Linux hardpillD 6.1.0-26-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.112-1 (2024-09-30) x86_64 GNU/Linux
## if you have never installed Docker you can skip the next step which removes old installations
dick@hardpillD:~$for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt remove $pkg; done
## Add Docker's official GPG keys and the Docker repository
dick@hardpillD:~$sudo apt -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin make
## you need to add yourself to the Docker group
dick@hardpillD:~$sudo usermod -aG docker $USER
## use the <newgrp> to put yourself in docker now
dick@hardpillD:~$newgrp docker
## clone the repo and then move (or copy) your <Portal> folder into <$HOME/portal64/vpk/>
## you should end with the structure $HOME/portal64/vpk/Portal
