Writing good Anki-cards is quite a bit of work. But it scales quite well. So take a look at the r2anki-notebooks in this repo, use and extend them as you see fit. Please also consider contributing your own Anki-cards via a pull-request.
This is a repo accompaning the r2anki-package.
You can clone the repo or download the files, export them to your Anki-collection via r2anki::r2anki() and give it a try.
Feedback is very welcome! :)
