+To enable HTTPS, you need to configure the `ROCKET_TLS`.
+
+The values to the option must follow the format:
+```
+ROCKET_TLS={certs="/path/to/certs.pem",key="/path/to/key.pem"}
+```
+Where:
+- certs: a path to a certificate chain in PEM format
+- key: a path to a private key file in PEM format for the certificate in certs
+
+```sh
+docker run -d --name bitwarden \
+  -e ROCKET_TLS='{certs="/ssl/certs.pem",key="/ssl/key.pem"}' \
+  -v /ssl/keys/:/ssl/ \
+  -v /bw-data/:/data/ \
+  -p 443:80 \
+  mprasil/bitwarden:latest
+```
+Note that you need to mount ssl files and you need to forward appropriate port.
+
+Due to what is likely a certificate validation bug in Android, you need to make sure that your certificate includes the full chain of trust. In the case of certbot, this means using `fullchain.pem` instead of `cert.pem`.
+
+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](https://certbot.eff.org/) will create a folder that contains the needed `fullchain.pem` and `privkey.pem` files in `/etc/letsencrypt/live/mydomain/`
+
+These files are symlinked to `../../archive/mydomain/privkey.pem`
+
+So to use from bitwarden container:
+
+```sh
+docker run -d --name bitwarden \
+  -e ROCKET_TLS='{certs="/ssl/live/mydomain/fullchain.pem",key="/ssl/live/mydomain/privkey.pem"}' \
+  -v /etc/letsencrypt/:/ssl/ \
+  -v /bw-data/:/data/ \
+  -p 443:80 \
+  mprasil/bitwarden:latest
+```
