In D7684 it was discussed that the way the Steam installation and upgrade instructions integration I had added to the manual weren't particularly clear. So the Steam integration into the manual has been split off to it's own task simply so D7684 could be accepted as it offered useful information for the manual that would be great to get in before 2.83 release.
The diff, in the first revision, is the exact same as it was when proposed in D7684. This means the integration still isn't that great. I would like to hear feedback from other users on what should be changed, added, or removed from the diff so the Steam installation and upgrade information can be added in to the manual in a straight forward way.
