 ## Install with URL prefix
 
-If you want to install octomode with an URL prefix, like <https://mydomainname.ext/octomode/>, then you can use the gunicorn WSGI. If you have ran the `make setup` command already, then `gunicorn` is already installed. Configure your application root URL in your `.env` file. You can simply run *octomode* now with the following command to run it with `gunicorn` (and not the built-in Flask dev server): `make action`
+If you want to install octomode with an URL prefix, like <https://mydomainname.ext/octomode/>, then you can use the gunicorn WSGI.

+Configure your application root URL in your `.env` file to `/octomode`:

+```
+OCTOMODE_APPLICATION_ROOT=/octomode
+```
+
+After that, you can simply run: 
+
+`make action`
