I think spaced repetition can be very helpful in language learning, but the author's plan of finding a pre-made deck of the most common 5,000 words is probably the worst way to use it. A much more effective approach is to create vocab cards yourself as you find new words through your immersion. Immersion could be anything from watching content online, to reading, to conversations with native speakers. From here you can skip the 500 or so most common words because those will appear exponentially more frequently and don't really require spaced repetition if you are regularly immersing. Also if you're not an engineer, or you don't want to fiddle with Anki plugins you can use Mochi [0] which has built in support for text-to-speech, dictionary lookup, transcription, etc. [0] https://mochi.cards/ https://mochi.cards/
