# requirement that is incompatible with it. In addition, `slim`
# ensures that everything is as small as possible (using Debian), for production
# use. We will use a multi-stage Dockerfile, in which firstly Orcha
# will be built and later on, it will use this as the base image
# for further runs to be faster and efficient.
