What's the layouts folder for in Rails?

I understand that .html.erb files go within app/views or its subfolders. But what is the app/views/layouts folder in particular for in Rails?

Layout in rails framework is very important folder, main layout of your application is define here as application.html.erb and all the views are yielded here using <% yield %>

app/views/layouts is the folder in which rails looks for the layouts.

From http://guides.rubyonrails.org/layouts_and_rendering.html#finding-layouts :

To find the current layout, Rails first looks for a file in app/views/layouts with the same base name as the controller. For example, rendering actions from the PhotosController class will use app/views/layouts/photos.html.erb (or app/views/layouts/photos.builder). If there is no such controller-specific layout, Rails will use app/views/layouts/application.html.erb or app/views/layouts/application.builder. If there is no .erb layout, Rails will use a .builder layout if one exists. Rails also provides several ways to more precisely assign specific layouts to individual controllers and actions.

What is a layout?

A layout defines the surroundings of an HTML page. It's the place to define common look and feel of the page.

The RailsCasts episode - All About Layouts - though very old, is still very useful in this context.
