# To build the image, run `docker build` command from the root of the
# repository:
#
# docker build -f docker/Dockerfile .
#
# There is an optional PYTHON_VERSION build argument which sets the
# version of python to build against. For example:
#
# docker build -f docker/Dockerfile --build-arg PYTHON_VERSION=3.9 .
#
#
# And an optional LIBOLM_VERSION build argument which sets the
# version of libolm to build against. For example:
#
# docker build -f docker/Dockerfile --build-arg LIBOLM_VERSION=3.2.11 .
#
##
## Creating a builder container

# then transfer those dependencies to the container we're going to ship,
# before throwing this one away
