Elixir v1.9 added mix release, we can now make releases without needing an external dependency! 🎉

Could a section for this command be added?

Also what do you think about the distillery section? 🤔 Checking the repo it states it is officially deprecated and may have problems with the newer versions of elixir. However I think its still widely used in projects developed before the release of mix releases, maybe a warning or info about this could be added.
