# Set up a development environment for the ePIC C example.
#
# Typical workflow for building the image and starting container:
#
#   sudo docker build -t epic .
#   sudo docker run -it epic /bin/bash
#
# Once inside container simply run make. This will take signficant time,
# memory and disk space because LLVM is built as part of the example.
#
#   make
