+### Enabling HTTPS
+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/ \
+  -v /icon_cache/ \
+  -p 443:443 \
+  mprasil/bitwarden:latest
+```
+Note that you need to mount ssl files and you need to forward appropriate port.
+
+### Enabling U2F authentication
+To enable U2F authentication, you must be serving bitwarden_rs from an HTTPS domain with a valid certificate (Either using the included
+HTTPS options or with a reverse proxy). We recommend using a free certificate from Let's Encrypt.
+
+After that, you need to set the `DOMAIN` environment variable to the same address from where bitwarden_rs is being served:
+
+```sh
+docker run -d --name bitwarden \
+  -e DOMAIN=https://bw.domain.tld \
+  -v /bw-data/:/data/ \
+  -p 80:80 \
+  mprasil/bitwarden:latest
+```
+
+Note that the value has to include the `https://` and it may include a port at the end (in the format of `https://bw.domain.tld:port`) when not using `443`.

 ### Other configuration
 
 Though this is unlikely to be required in small deployment, you can fine-tune some other settings like number of workers using environment variables that are processed by [Rocket](https://rocket.rs), please see details in [documentation](https://rocket.rs/guide/configuration/#environment-variables).
