  3. From Anki's main window, head to ToolsAdd-ons
  4. Drag-and-drop the .ankiaddon package onto the add-ons list
  5. Restart Anki


The installation and use of this add-on is detailed in the Wiki and a series of video tutorials on YouTube. More information may also be found in the AnkiWeb description.
