 Note that you need to mount ssl files and you need to forward appropriate port.
 
+Softwares used for getting certs are often using symlinks. If that is the case, both locations need to be accessible to the docker container.
+Example: certbot will create a folder that contains the needed cert.pem and privacy.pem files in /etc/letsencrypt/live/mydomain/
+
+These files are symlinked to ../../archive/mydomain/mykey.pem
+
+So to use from bitwarden container:
+
+```sudo docker run -d --name bitwarden \
+  -e ROCKET_TLS='{certs="/ssl/live/mydomain/cert.pem",key="/ssl/live/mydomain/privkey.pem"}' \
+  -v /etc/letsencrypt/:/ssl/ \
+  -v /bw-data/:/data/ \
