+    - run as server with PORT=5000 marp -s ./slides
+    - requires wget for download
+    - requires chrome to convert to pdf
+ - docker container https://hub.docker.com/r/marpteam/marp-cli/
+`docker run --rm --init -v $PWD:/home/marp/app/ -e LANG=$LANG marpteam/marp-cli slide-deck.md --pdf`
+ - Run marp cli in its own docker container in server mode!!!
+    - output folder as volumne, so that marp container can assess it
+
 powerpoint export is also possible with --pptx
 
+ - use config
+    - run using cli command when in prod mdoe (inside docker)
+    - run using docker when in dev mode
