+## Hosting
+
+For hosting we package interactive_RSE_comp_plot.py into a Docker image.
+We mount a fixed size ext4 formatted file and use it as a volume to store the submissions, to cap the maximum used disk space.
+
+The mountable file, `submissions.volume`, and the mount point, `submissions`, are created by executing
+
+```
+sh create_volume.sh
+```
+
+which makes sure to not override an existing file.
+
+We build the Docker image and run a container based on it by executing
+
+```
+sh build_and_start.sh
+```
+
+This will also rebuild and restart if applicable.
+
+As it is configured right now, the services is reachable on port 9000 on the host.
