HerediVar was developed and tested on Linux Ubuntu 20.04. So the following steps assume you are using this operating system.

-## TLS
-HerediVar was set up such that it runs behind an http-server (like Apache or NGINX) in reverse proxy mode. Thus, HerediVar itself does not consider TLS and should only run on localhost without direct access to the public domain. TLS should be implemented in a production environment by the public facing http-server.
