Instructions for upgrading ruby-install
Currently, the README doesn't say how to upgrade to the latest ruby-install (which is necessary, e.g. for installing TruffleRuby).
For instance ruby-build has an explicit section for this: https://github.com/rbenv/ruby-build#upgrading
Is upgrading the same as the Install instructions ? I guess that's mostly fine but it might leave some files behind. In any case, it would be worth mentioning how to upgrade in the README.
I've also played with running bin/ruby-install from a git checkout and that seemed to work well.
So it doesn't seem necessary to run make install.
Maybe we should mention that as a possibility in the README?
Depending on your operating system, but when I’m using Ubuntu I’m managing ruby-install and chruby with Linuxbrew (with non-standard installation location because I don’t want to share it with other users).
If you installed ruby-install directly from source, and not a package manager, then upgrading is as simple as performing the same installation as the previous ruby-install version; this is standard behavior for the vast majority of *nix command-line utilities AFAIK. Should we add another section listing all of the upgrade commands for the various package managers that offer ruby-install?
