 _Prerequisites_
 
 You will need:
 
-* A computer with an x86 processor running Linux. We're going to slowly escape
-  Linux, but we'll need it at the start. Mu works on other platforms, but be

+  platforms will also do (BSD, Mac OS, Windows Subsystem for Linux), but be
   warned that things will be _much_ (~20x) slower.
 * Some fluency in typing commands at the terminal and interpreting their
   output.
