# you can use this to build elixir then copy relevant files to your local machine. Note that directories
# must be copied in exact same locations since paths are hard coded in erlang/elixir builds. So
# copy /opt/erlang from container to /opt/erlang on your local machine:
   ## docker cp elixir:/opt/elixir /opt
   ## docker cp elixir:/opt/erlang /opt
   ## Add /opt/erlang/bin and /opt/elixir/bin to your PATH
   ## If you get utf-8 warning while starting iex, copy lines with `apt install locales` and update-locale from above RUN
   ## statement to your local machine
