+### Enable SSL Traffic
+
+Our Nginx config has SSL enabled by default, but it does require you to provide your certificate first, copy here your certificate files as `kibana-access.pem` and `kibana-access.key`.
+
+The final tree should be like this:
+
+```
+nginx_conf/
+├── kibana.htpasswd
+├── kibana-web.conf
+└── ssl
+    ├── kibana-access.key
+    └── kibana-access.pem
+```
+
+
+
+#### Using a Self Signed Certificate
+
+In case you want to use a self-signed certificate we provided a script to generate one. You may create your own with more relevant information.
+
+Execute `bash generate-self-signed-cert.sh` on this same directory and the right files will be generated. You must have installed `openssl` locally.
