+# HTTPS
+
+Always use HTTPS especially with a terminal to your server. You can add HTTPS by
+either using WeTTY behind a proxy or directly.
+
+See docs for [NGinX](./nginx.md) and [Apache](./apache.md) for running behind a
+proxy.
+
+To run WeTTY directly with SSL use both the `--ssl-key` and `--ssl-cert` flags
+and pass them the path too your cert and key as follows:
+
+```bash
+wetty --ssl-key key.pem --ssl-cert cert.pem
+```
+
+If you don't have SSL certificates from a CA you can create a self signed
+certificate using this command:
+
+```bash
+openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 30000 -nodes
+```
