Its quite difficult for anyone who is newish to linux to do an RVM installation using the provided instructions: https://rvm.io/rvm/install/ - the instructions are not very clear. They also recommend reading the installation script, which is long and scary: "I recommend you read the installation script yourself. This will give you a chance to understand what it is doing before installing, and allow you to feel more comfortable running it if you do so." ... https://github.com/wayneeseguin/rvm/blob/master/binscripts/r...
