These instructions are currently for Fedora 30. I'll update them over the releases if anything changes.
Press the Win/Super key, type software
and press Enter.
Click the Menu Button (☰) and choose Software Repositories. Now enable "Third Party Software" and "RPM Fusion ... Steam"
Press the Win/Super key, type terminal
and press Enter.
sudo dnf update --refresh
Also it doesn't hurt to reboot to make sure you're on the latest linux kernel.
sudo dnf install steam -y
You can either open it from Activities or press the Win/Super key, type steam
and press Enter.
Accept the agreement and it'll download the latest version of Steam.

dnf upgrade
had failed to complete previously. So I re-installed all the packages and then installed steam. Commands:You can read more about this in this answer https://superuser.com/questions/994151/conflicts-between-new-32-bit-and-old-64-bit-packages-when-installing-rpmfusions
