+# Customizing other Ruby classes
+
+Other than models, controllers and components, there are a few other folders containing Ruby code:
+
+* `app/form_builders/`
+* `app/graphql/`
+* `app/lib/`
+* `app/mailers/`
+
+The files in these folders can be customized like any other Ruby file (see [customizing models](models.md) for more information).
+
+For example, in order to customize the `app/form_builders/consul_form_builder.rb` file, create a file `app/form_builders/custom/consul_form_builder.rb` with the following content:
+
+```ruby
+load Rails.root.join("app", "form_builders", "consul_form_builder.rb")
+
+class ConsulFormBuilder
+  # Your custom logic here
+end
+```
+
+Or, in order to customize the `app/lib/remote_translations/caller.rb` file, create a file `app/lib/custom/remote_translations/caller.rb` with the following content:
+
+```ruby
+load Rails.root.join("app", "lib", "remote_translations", "caller.rb")
+
+class RemoteTranslations::Caller
+  # Your custom logic here
+end
+```

+# Personalización de otras clases de Ruby
+
+Aparte de modelos, controladores y componentes, hay otros directorios que contienen código de Ruby:
+
+* `app/form_builders/`
+* `app/graphql/`
+* `app/lib/`
+* `app/mailers/`
+
+Los ficheros en estos directorios pueden personalizarse como cualquier otro fichero de Ruby (véase [personalización de modelos](models.md) para más información).
+
+Por ejemplo, para personalizar el fichero `app/form_builders/consul_form_builder.rb`, crea el archivo `app/form_builders/custom/consul_form_builder.rb` con el siguiente contenido:
+
+```ruby
+load Rails.root.join("app", "form_builders", "consul_form_builder.rb")
+
+class ConsulFormBuilder
+  # Your custom logic here
+end
+```
+
+O, para personalizar el fichero `app/lib/remote_translations/caller.rb`, crea el archivo `app/lib/custom/remote_translations/caller.rb` con el siguiente contenido:
+
+```ruby
+load Rails.root.join("app", "lib", "remote_translations", "caller.rb")
+
+class RemoteTranslations::Caller
+  # Your custom logic here
+end
+```
