 ## Runtime dependencies and known issues
 
-Some VST plugins might require you to manually install some dependencies. The

+Any VST2 plugin should function out of the box, although some plugins will need
+some additional dependencies for their editor GUIs to work correctly. Notable
+examples include:
 
 - **Serum** requires you to disable `d2d1.dll` in `winecfg` and to install
   `gdiplus` through `winetricks`.
 
+Aside from that, these are some known caveats:
+
+- Most recent **iZotope** plugins don't have a functional GUI in a typical Wine

+- Dragging and dropping files onto plugin editors works, but the editor does not
