Looks like Phoenix has changed the default distribution of template code to separating it into a main “root” part in root.html.eex that includes the HTML header and putting in the body via “app.html.eex”. So the book should change that.

Also ` <%= render @view_module, @view_template, assigns %>` should be changed to `<%= @inner_content %>`. This should also be applied on Page 57.
