 # Slimmer Templates
 
+## `gem_layout`
+
+This template uses the [public layout component] from the GOV.UK Publishing Components gem. It supplies the header and footer only - this includes the cookie banner, skip to content link, header bar, emergency banner, survery banner, global bar, feedback, and footer. The content is constrained and centred.
+
+## `gem_layout_full_width`
+
+This is the same as the `gem_layout` template, except that this layout **doesn't** constrain and centre the content to the same width as the GOV.UK header.
+
+Use this layout if you want to have full width content - such as the blue welcome bar on the GOV.UK homepage.
+
 ## `core_layout` (default)
 
-This template contains styles for the black header bar, the footer and core
-layout classes. By default it will center your content to the same width as the
-GOV.UK header. It provides classes for grid layouts using the column mixins
-from the frontend toolkit.
