Steam Is Now Available In Flatpak Form
There's been a few different groups investigating Steam in a Flatpak or Snappy environment while this morning Steam appeared on Flathub. Flathub is a build and distribution service around Flatpak.
A reader tipped us off to com.valvesoftware.Steam being added to Flathub. Its JSON file is what's interesting if you are curious about what the package allows for Steam, etc.
