+# Element: Group Role Indicator
+
+Toggles the visibility of an indicator based on the unit's current group role (tank, healer or damager).
+
+## Widget
+
+GroupRoleIndicator - A `Texture` used to display the group role icon.
+
+## Notes
+
+A default texture will be applied if the widget is a Texture and doesn't have a texture or a color set.
+
+## Examples
+

+    local GroupRoleIndicator = self:CreateTexture(nil, 'OVERLAY')
+    GroupRoleIndicator:SetSize(16, 16)
+    GroupRoleIndicator:SetPoint('LEFT', self)
