+# Dymola Docker
+
+## Disclaimer
+This is just an unofficial experiment by me.
+It seems to work, but no guarantee!
+This is based on the files provided by the RWTH Aachen for teaching.
+
+## Building
+You need a running docker engine and X11.
+First you need to download the files (program files (rpm) and license file).
+Copy the folder `AM_CAT_Dymola.AllLinux` and `Dymola.LIC` in the same folder as the `Dockerfile`.
+```bash
+sudo docker build -t dymola .
+```
+This may take a while.
+
+## Running
+There are a number of ways, but I use:
+```bash
+sudo docker run -it --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v /path/to/my/dymola/workspace:/home/user/Dymola dymola
+```
+You can then run Dymola in the opened `xterm` (terminal):
+```bash
+dymola-2018-x86_64
+```
+This requires you to always set the path to the license file and the workspace on each start.
