It has come to our attention that the temporary Dockerfile description for mediawiki in local-charts may not work if the user has not already run composer in their mediawiki repository. If the standard mediawiki docker image (work in progress) is not yet complete, this should be fixed.
It was suggested to move the Dockerfile descriptions from the README to their own files. If that is done, the README should be updated with instructions for what to do with the Dockerfiles for each service.
It was also suggested to move instructions for "optional" services to their own section in the README.
