Actually these links are for updated installation guides that I just released this evening.  Hopefully this sorts out a lot of your questions.  I already posted it in the new ANN thread but I wanted to get it here in case some of you aren't watching the other one yet.

I am very pleased to release a new start-to-finish masternode installation guide for Vultr.  This installation method allows you to install multiple Helium masternodes on the same VPS by using IPv6.  The written guides are very helpful for a lot of people, but for others they find it easiest to watch someone else go through the steps so if you happen to be one of the latter, I believe you'll find this very helpful.

You can watch the video on Youtube at https://youtu.be/mj1FyN6Wauk

There is also a written guide which you can review on Medium that contains some more pictures and allows you to copy and paste some of the scripts and commands that are used in the video.  https://medium.com/@AKcryptoGUY/securely-install-multiple-helium-masternodes-3ee2e995a5e0
