-- UNFINISHED LIST ------------------------------------------------ src/Main.elm

I cannot find the end of this list:

12| update msg model = [
13|   case msg of
14|     Increment ->
15|       model + 1
16| 
17|     Decrement ->
18|       model - 1
                   ^
You can just add a closing ] right here, and I will be all set!
