Rocket.Chat Install Tutorial

I have found and tried several sets of install instructions both in the forum, and on the net, but none have worked completely.

I'm looking for instructions to install Rocket.Chat on Centos6 VPS.

Thanks.

If you have a dedicated server, I can help you with that..  I've done few installation on my dedicated server, but not on shared hosting which can be a nightmare at times because the hosting company might not give you the permission you need..

It's a VPS system. Do you have the instructions steps?
