-
-- `**(FREE)**` displays as **(FREE)**
-- `**(FREE SELF)**` displays as **(FREE SELF)**
-- `**(FREE SAAS)**` displays as **(FREE SAAS)**
-
-The `**(FREE)**` generates a `span` element to trigger the
-badges and tooltips (`<span class="badge-trigger free">`).
+Do not add tier badges inline with other text. The single source of truth for a feature should be the heading where the functionality is described.
