Please explain, or add link to references

Here I'd like to point out that your Medium tutorial is not a tutorial by itself, at the moment it's just a bunch of code mirrored from GitHub. Mind you, I'm not telling this for the sake of blaming your (hard) job, but as you have pointed out at the end of the post, you didn't explain a lot of niches.

"I am so sorry, because I can’t explain this tutorial clearly."

So I'm opening this issue to invite the community to contribute with guided comments or links. Have a nice day!

It would also be good to see some tests because a huge benefit of an architecture is to test thoroughly.
