     Default settings are stored in the `variables.env`. You may want to change things to adjust RDMO to your local needs. As `variables.env` is part of the repo and would get overwritten if you pulled again the `makefile` contains a logic that lets you use a file called `variables.local` instead. If such a file exists the settings will be loaded from there. Simply copy `variables.env` to `variables.local` and feel free to change whatever you want.
 
+    Please note that you might need to change the `ALLOWED_HOSTS` entry depending on your server setup. The URL or IP under which RDMO is served needs to be allowed by putting it into the list. Usually the allowed hosts are declared in the `local.py`. In this docker compose setup we decided to move it into the environment variables and so the `variables.env` to raise awareness that the setting might need to be adjusted.
