title: How to install SSReflect and MathComp in Linux?
body: <p>I have successfully installed Coq 8.6 and CoqIDE in Linux (Ubuntu 17.04). However, I don't know to proceed in order to add SSReflect and MathComp to this installation. All the references that I have checked seemed to be very confusing to me. Does anyone have a straight and simple recipe to that? I do have opam installed.</p>
