New to elm. I have a small kata done in Elm, want to move it to 19. What’s the recommended path?

- for the binary, I assume most use Homebrew to install elm which installs v19 (_brew install elm_)
- I see the [manual steps](https://github.com/elm/compiler/blob/master/upgrade-docs/0.19.md) option
- I see [elm-upgrade](https://github.com/avh4/elm-upgrade)

There is no html in my v18 project.

What has been your experience with the manual vs. elm-upgrade?

I installed `Elm` on my Mac using the standard installer: [https://guide.elm-lang.org/install.html](https://guide.elm-lang.org/install.html)

Before doing that, I backed up `/usr/local/bin/elm*` to `/usr/local/bin/elm-0.18/`.

I used `npm install -g elm-ugrade` and `npm install -g elm-test@beta` to get `elm-upgrade` and `elm-test`.

I always start with `elm-upgrade`, then do what’s necessary to make it build again by hand. Usually it just works after that, but sometimes it takes a little more work, especially if I have to work around a feature that was removed by 0.19.
