 	</brief_description>
 	<description>
+		A dummy [TextServer] interface that doesn't do anything. Useful for freeing up memory when rendering text is not needed, as text servers are resource-intensive. It can also be used for performance comparisons in complex GUIs to check the impact of text rendering.
+		A dummy text server is always available at the start of a project. Here's how to access it:
+		[codeblock]
+		var dummy_text_server = TextServerManager.find_interface("Dummy")
+		if dummy_text_server != null:
+		    TextServerManager.set_primary_interface(dummy_text_server)
+		    # If the other text servers are unneeded, they can be removed:
+		    for i in TextServerManager.get_interface_count():
+		        var text_server = TextServerManager.get_interface(i)
+		        if text_server != dummy_text_server:
+		            TextServerManager.remove_interface(text_server)
+		[/codeblock]
+		The command line argument [code]--text-driver Dummy[/code] (case-sensitive) can be used to force the "Dummy" [TextServer] on any project.
