 \subsection master-ISDD-1-ex-1 Exercise 1: Computing and printing simple collective variables
 
 In this exercise, we will make practice with computing and printing collective variables.
-To analyze the trajectories provided here, you should:
-- Create a PLUMED input file with a text editor (let us call it `plumed.dat`) similar to the one above;
-- Run the command `plumed driver` (see below).
+To analyze the trajectories provided here, we will:
+- create a PLUMED input file with a text editor (typically called `plumed.dat`) similar to the one above;
+- run the PLUMED \ref driver utility.
 
 Notice that you can also visualize trajectories with VMD directly. 
 For example, the trajectory `traj-whole.xtc` can be visualized with the command:
