+#### `MetaTags`
+
+A super simple way to define and render meta tags in your Phlex views. Just render the
+`Phlexible::Rails::MetaTagsComponent` component in the head element of your page, and define the
+meta tags using the `meta_tag` method in your controllers.
+
+```ruby
+class MyController < ApplicationController
+  meta_tag :description, 'My description'
+  meta_tag :keywords, 'My keywords'
+end
+```
+
+```ruby
+class MyView < Phlex::HTML
+  def template
+    html do
+      head do
+        render Phlexible::Rails::MetaTagsComponent
+      end
+      body do
+        # ...
+      end
+    end
+  end
+end
+```
