Configuring HTTPS on Mendelson 1.1 b51

Hi All,
I am new to Mendelson so please bear with me. I am using Mendelson 1.1 b51, I am able to successfully send messages via HTTP. Now I want to implement sending messages in HTTPS, so far from what I have read from articles and here on community I need to uncomment the SSL config in jetty.xml which I already did.
Now, what is the next step? do I need to also update my MDN url from what is set in jetty.xml?

I am following this guide… but it seems its outdated, where can I find the guides on how to implement HTTPS for Mendelson?
