+### MuseScore 4
+
+As of writing, the MuseScore 4 (MS4) plugin environment is still a work in progress. Nevertheless, a version for MS4 is available, with the following limitations:
+
+* Dialog. Docked plugins are currently unavailable, forcing the plugin to be a dialog.
+* Fixed dimensions. On some resolutions, the dialog box may be too small or big. I've added an option to the dimensions in the settings.
+* Jank text input UI in settings. QML `TextField` doesn't work for now, so please bear with it.
+
+Also, FYI note that the `ElementType` codes have changed between MS4 and MS3. See the table in [Settings](#settings).
