-  curl -kL <host>[/ip|/host|/xff|/ua|/headers|/city|/country]
-  wget --no-check-certificate -qO - <host>[/ip|/host|/xff|/ua|/headers|/city|/country]

+  $ wget -qO - <host>:8080

-  Or navigate to `<host>` from your browser. It will automatically redirect to https and you have to accept the self-signed certificate.
+
+  Or navigate to `http://<host>:8080` from your browser.
+
+* If runing `ipask` with nginx reverse proxy:
+  ```sh
+  $ curl -kL <host>
+  $ wget --no-check-certificate -qO - <host>
+  ```
+
+  Or navigate to `<host>` from your browser. It will automatically redirect to https.
