-  1. Do the [The Ruby on Rails Guides: Getting Started](https://guides.rubyonrails.org/getting_started.html) project through section 9.2, from the Rails Guides.

However, if you want to explore additional functionality of deleting or basic authentication, you can do Section 10 and 11.

   4. Pay attention to any error messages you get as you build the app, even though they'll be unplanned.  You'll see all these messages again and again when you're building Rails apps, so it's helpful to start getting familiar with which portions of the message you should pay attention to (and maybe put into Google if you can't figure out what caused it).
