You can probably copy only Python files and You can use This file will tell You can probably copy only Python files and `requirements.txt`. We don't need anything else in the image to run the app.
You can use `.dockerignore` file to acomplish that. Check [this documentation](https://docs.docker.com/engine/reference/builder/#dockerignore-file) and [my example](https://git.skobk.in/skobkin/magnetico-web/src/branch/master/.dockerignore).
This file will tell `ADD`/`COPY` to ignore some files you don't want to see in the image.

I just understood that I think it's a good idea to fix that. I just understood that `README.md` has no documentation about running the bot in Docker yet.
I think it's a good idea to fix that.
