 The `view` DSL method declares the filename of the view where an
-`element` is implmented.
+`element` is implemented.
 
-The `element` DSL method in turn declares an element and defines a value
-to match to the actual view code. It is possible to use `element` with value,
-with a String value or with a Regexp.
+The `element` DSL method in turn declares an element for which a corresponding
+`qa-element-name-dasherized` CSS class need to be added to the view file.
+
+You can also define a value (String or Regexp) to match to the actual view
+code but **this is deprecated** in favor of the above method for two reasons:
+
+- Consistency: there is only one way to define an element
+- Separation of concerns: QA uses dedicated CSS classes instead of reusing code
+  or classes used by other components (e.g. `js-*` classes etc.)
 
 ```ruby
 view 'app/views/my/view.html.haml' do
+  # Implicitly require `.qa-logout-button` CSS class to be present in the view
+  element :logout_button

+  ## This is deprecated and forbidden by the `QA/ElementWithPattern` RuboCop cop.
