+### New versions

+When improvements are made, we can update the deployed version like so:
+
+```shell
+cd /opt/home73k
+git pull
+mix deps.get --only prod
+MIX_ENV=prod mix compile
+# update Pygments in venv
+priv/pygments/bin/pip3 install -U Pygments
+# rebuild static assets:
+npm run deploy --prefix ./assets
+MIX_ENV=prod mix phx.digest
+MIX_ENV=prod mix release --overwrite
+# test starting it:
+MIX_ENV=prod _build/prod/rel/home73k/bin/home73k start
