 ### Prerequisites: 
 - User must have the folder ./configs volumed within docker so that it is retained during updates.
 - Docker uses must download the security jar version by setting ``DOCKER_ENABLE_SECURITY`` to ``true`` in environment variables. 
-- Now the initial user must be generated. Navigate to your settings.yaml and configure your security settings along with the username and password (only required on the first boot to create the initial user, ignored after.). Alternatively, you can set these via the environment variables ``SECURITY_ENABLELOGIN : true`` ``SECURITY_INITIALLOGIN_USERNAME: username`` ``SECURITY_INITIALLOGIN_PASSWORD: password``
+- Then either enable login via the settings.yml file or via setting ``SECURITY_ENABLE_LOGIN`` to ``true``
+- Now the initial user will be generated with username ``admin`` and password ``stirling``. On login you will be forced to change the password to a new one. You can also use the environment variables ``SECURITY_INITIALLOGIN_USERNAME`` and  ``SECURITY_INITIALLOGIN_PASSWORD`` to set your own straight away (Recommended to remove them after user creation).

+### Q3: Why is my download timing out
+NGINX has timeout values by default so if you are running Stirling-PDF behind NGINX you may need to set a timeout value such as adding the config ``proxy_read_timeout 3600;``
