Hi!

Great book so far, I’m learning a lot! 😃

The errata I found is at page 136, right when we are creating the promo LiveView. We are instructed to create a live view (promo\_live.ex) with a `.header` and a `.simple_form`. Then, we are shown a picture of what we should see: the title and the subtitle, but no form. Furthermore, if we go to _/promo_ we see an error because `@form` is not yet initialised at this point.

Removing the `.simple_form` from the first excerpt of code would fix this. It is not a big deal because it gets fixed when you code the next instructions (the `mount` fn and so on). Still, just so you know.

Thanks!
