Where installation via package manager is available, can we switch to using that?

We're on the same page! I am thinking that when I add the repos I should make the initial install request specifying the version as the version that comes down in the version tag on git. That way if there happens to a sync issue where a newer than the latest "official" release is hanging around, this code only installs the official release tagged as latest on git?

I think it should just install the latest version from the repo. Eventually, we will have a non-pre-release version, and I think then we have a decision to make, but currently, if it's in the repo, it's ready.
