Node.js 8 as required by the software isn't provided on CentOS

[RubenAstudillo]

Hi

On the documentation is said the required version on node.js is 8 a shown in the image

But on CentOS, which is a supported platform(?), the node.js version provided by the EPEL repos is 6.17.1 . Either there is an extra repository we should install (and be told which is it) or the instructions are wrong. I think it's the first option as that node version is really old and only is provide to maintain compatibility with RHEL. Could you fix this?
