+## MiKTeX docker image
+
+A MiKTeX docker image was build, because of [mitkex#1370](https://github.com/MiKTeX/miktex/issues/1370).
+In October 2023, there was an update to the [MiKTeX Docker image](https://github.com/MiKTeX/docker-miktex/tree/master) with following run recommendation:
+
+    docker run -ti -v miktex:/var/lib/miktex -v `pwd`:/miktex/work -e MIKTEX_UID=`id -u` miktex/miktex:essential pdflatex sample2e.tex
+
+The main difference is that the mwe-miktex Dockerfile
+
+- additionally installs `cm-super`
+- Exectues following commands
+  - `RUN miktex --verbose fontmaps configure`
+  - `RUN miktex --verbose fndb refresh`
+  - `RUN initexmf --admin --verbose --update-fndb`
