# Note:
#
#   This Dockerfile sets up everything for studying Japanese with Anki. ADAPT
#   comments point to what you'll probably need to adapt to your situation.
#
# Prepare (example):
# 
#   $ mkdir AnkiDocker
#   $ cd AnkiDocker
#   $ # Save this file to Dockerfile and adapt it to your needs.
#   $ mkdir config
#   $ docker build -t debian-anki .
#
# Run (example):
#
#   $ docker run -ti --rm -e DISPLAY=unix$DISPLAY \
#         -v $HOME/Anki:/home/anki-user/Anki \
#         -v $(pwd)/config:/home/anki-user/.config \ # ADAPT – This is for 
#         -v $HOME/.anthy:/home/anki-user/.anthy \   # Japanese IME.
#         -v $HOME/.Xauthority:/home/anki-user/.Xauthority \
#         --net=host debian-anki
