 		Object that holds the project-independent editor settings. These settings are generally visible in the [b]Editor &gt; Editor Settings[/b] menu.
-		Accessing the settings is done by using the regular [Object] API, such as:
+		Property names use slash delimiters to distinguish sections. Setting values can be of any [Variant] type. It's recommended to use [code]snake_case[/code] for editor settings to be consistent with the Godot editor itself.
+		Accessing the settings can be done using the following methods, such as:
 		[codeblock]
-		settings.set(prop,value)
+		# `settings.set("some/property", value)` also works as this class overrides `_set()` internally.
-		settings.get(prop)
+		settings.set_setting("some/property",value)
-		list_of_settings = settings.get_property_list()
+
+		# `settings.get("some/property", value)` also works as this class overrides `_get()` internally.
+		settings.get_setting("some/property")
+
+		var list_of_settings = settings.get_property_list()
 		[/codeblock]
 		[b]Note:[/b] This class shouldn't be instantiated directly. Instead, access the singleton using [method EditorInterface.get_editor_settings].
