+## Run WeTTY behind nginx
+
+As said earlier you can use Nginx to add https to WeTTY.
+
+**Note** that if your proxy is configured for https you should run WeTTY without
+SSL
+
+If you configure nginx to use a base path other than `/wetty`, then specify that
+path with the `--base` flag, or the `BASE` environment variable.
+
+The following confs assume you want to serve WeTTY on the url
+`example.com/wetty` and are running WeTTY with the default base and serving it
+on the same server
+
+For a more detailed look see the
+[nginx.conf](https://github.com/butlerx/wetty/blob/main/conf/nginx.template)
+used for testing
+
+Put the following configuration in your nginx conf:
+
+```nginx
+location ^~ /wetty {
+  proxy_pass http://127.0.0.1:3000/wetty;
+  proxy_http_version 1.1;
+  proxy_set_header Upgrade $http_upgrade;
+  proxy_set_header Connection "upgrade";
+  proxy_read_timeout 43200000;
+
+  proxy_set_header X-Real-IP $remote_addr;
+  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+  proxy_set_header Host $http_host;
+  proxy_set_header X-NginX-Proxy true;
+}
+```
