+  Ash resource representing global application settings.
+
+  ## Overview
+  Settings is a singleton resource that stores global configuration for the association,
+  such as the club name and branding information. There should only ever be one settings
+  record in the database.
+
+  ## Attributes
+  - `club_name` - The name of the association/club (required, cannot be empty)
+
+  ## Singleton Pattern
+  This resource uses a singleton pattern - there should only be one settings record.
+  The resource is designed to be read and updated, but not created or destroyed
+  through normal CRUD operations. Initial settings should be seeded.
+
+  ## Environment Variable Support
+  The `club_name` can be set via the `ASSOCIATION_NAME` environment variable.
+  If set, the environment variable value is used as a fallback when no database
+  value exists. Database values always take precedence over environment variables.
+
+  ## Examples
+
+      # Get current settings
+      {:ok, settings} = Mv.Membership.get_settings()
+      settings.club_name  # => "My Club"
