Nice article. It makes sense in retrospect, but I didn’t know you could handle global processes in the supervision tree by handling the already-started error and link+return the other pid. Cool trick 👍

I think it would be worth mentioning [Highlander](https://hex.pm/packages/highlander) in your article as well. It provides the same functionality as the SingletonManager proposed.
