Why are there no images?
The short answer is to minimize hosting costs as much as possible and make the page load faster. Running this library is not free and it definitely won’t be profitable in the short term. That’s why we decided to make it text-only, with very specific exceptions where images are needed as examples.
Why are there no videos?
Same reason as images — videos are heavier than images and it’s not cost-effective in the short term. We hope to eventually add some relevant YouTube videos for the topics.
