This extension simplifies adding new words to your Anki flashcards as you encounter them browsing the web.

To make it work with Anki, the app has to be open and AnkiConnect plugin should be installed. To install the AnkiConnect plugin:

1. Open the Install Add-on dialog by selecting Tools > Add-ons > Browse & Install in Anki.
   
2. Input 2055492159 into the text box labeled Code and press the OK button to proceed.
   
3. Restart Anki when prompted to do so in order to complete the installation of AnkiConnect.

To add the current translation to your Anki decks, press the Anki icon at the top of the translation pop-up. Note that the content of the translation block is completely editable, so you can modify your card even using some html.

You can also choose the deck to add the card into. You can pin the extension to the toolbar, so that you can open it as needed to either enter text or see it populated based on current selection.
