+# Show Rails Models With Pry
+
+With the [`pry-rails`](https://github.com/rweng/pry-rails) gem, you get some
+extra goodies in the Rails console for your project. One of those goodies is
+`show-models`, a command for printing out a list of all models in the rails
+project. Add and bundle the `pry-rails` gem, run `rails c`, and then run
+`show-models` to give it a go.
+
+```
+> show-models
+Pokemon
+  id: integer
+  name: string
+  level: integer
+  pokemon_type: varchar
+  belongs_to Trainer
+  created_at: datetime
+  updated_at: datetime
+Trainer
+  id: integer
+  name: string
+  has_many Pokemons
+```
