The github repo doesn’t have any code that corresponds to this part 3. However, I’ve worked through it, and you can find the results at https://github.com/marick/eecrit/tree/Tutorial_3_finished (Note, there are also tags for two intermediate steps, both with the prefix “Tutorial_3”.
Note: Because I was applying this to an existing repo that’s not about blog posts, I changed some of the names to match my domain. The main file is `web/elm/Registration.elm` rather than `Main.elm`. Throughout the code, I use the token “animalChoice” instead of “article”.
