+	Helper class to handle INI-style files.
 	</brief_description>
 	<description>
+	This helper class can be used to store [Variant] values on the filesystem using an INI-style formatting. The stored values as referenced by a section and a key. The stored data can be saved to or parsed from a file, though ConfigFile objects can also be used directly with accessing the filesystem.
+	The following example shows how to parse a INI-style file from the system, read its contents and store new values in it:
+	[codeblock]
+	var config = ConfigFile.new()
+	var err = config.load("user://settings.cfg")
+	if err == OK: # if not, something went wrong with the file loading
+	    # Look for the display/width pair, and default to 1024 if missing
+	    var screen_width = get_value("display", "width", 1024)
+	    # Store a variable if and only it hasn't been defined yet
+		if not config.has_section_key("audio", "mute"):
+		    config.set_value("audio", "mute", false)
+	    # Save the changes by overwriting the previous file
+		config.save("user://settings.cfg")
