I've uploaded a new kind of Docker image to the Hub, based on choosenim instead of manually built binaries: [https://cloud.docker.com/u/nimlang/repository/docker/nimlang/choosenim](https://cloud.docker.com/u/nimlang/repository/docker/nimlang/choosenim)
So, if you need an image for Nim 0.20.0 and don't care that much about its size, feel free to pull nimlang/choosenim. If you need devel version, just add choosenim devel to your Dockerfile.
