The docker image comes from https://cloud.docker.com/repository/docker/timhoar/dart_docs
container to run FORD to generate documentation for DART
Make sure docker is running -
cd /git/DART
docker run -it -v `pwd`:/work timhoar/dart_docs
cd /work/docs
ford ford_config.md
The best description of options for the FORD config are here: https://github.com/Fortran-FOSS-Programmers/ford/wiki/Project-File-Options
Also - this container also supports pandoc - which can (among other things) convert html to md.

The most trivial example would be:
pandoc -o bob.md bob.html
