(1) In anki, download the AnkiHub add-on (1322529746)
(2) Restart anki
(3) On web browser, subscribe to the endeavoroverhaul deck
(4) In anki, you should now see a ‘Ankihub’ button on the banner at top of screen. Press this button and go to ‘sync with ankihub.’ The ‘endeavoroverhaul’ deck should be there, ready for installation.
I’m also a VERY big newbie at anki so I hope the above steps work (this is what a remember doing, but there’s definitly a possibility a missed/mixed a step(s))!
